1Telescope Basics

We all have different ways of enjoying the starry night. The road to success in comfortable star
watching is to choose an astronomical instrument that matches you.

1 Understanding the basics of Astronomical Telescopes
What do you want to see through the astronomical telescope?
Are you interested in using it for taking astrophotography? Do
you need to travel somewhere to do astrophotography? It will be
n e c e s s a r y f o r y o u t o c h o o s e t h e a s t ro n o m i c a l t e l e s c o p eaccording to your purposes. However, the best telescope for you
i s t h e o n e y o u w i l l u s e t h e m o s t . We s y s t e m i z e V i x e n
astronomical telescopes to work for upgrades according to anincrease in the knowledge and experience of the users.

Effective Aperture of Objective Lens
The larger the effective aperture,
the bigger the telescope tube.

2 Aperture and Focal Length
The heart of an astronomical telescope is an optical tube thatis composed of a lens or mirror for collecting light and an
eyepiece for viewing with an eye. There are three maincategories of astronomical telescopes; refractors, reflectors,
and catadioptrics, and used for purposes and celestial objects
suitable for each.
One of the criteria for choosing an astronomical telescope is its
aperture (effective diameter of an objective lens or primary
mirror). The principal purpose of astronomical telescopes is tocollect as much as light from faint celestial objects. The larger
the telescope's aperture, the more it gathers light, and theb r i g h t e r i m a g e s w i l l re s u l t . I t i s a n a d v a n t a g e i n v i s u a lobservation and astrophotography.

3 Understanding Magnification
A telescope's focal length and a focal length of an eyepiece arefactors of magnification. Dividing the focal length of thetelescope by the focal length of the eyepiece yields
m a g n i f i c a t i o n . Yo u c a n c h a n g e t h e m a g n i f i c a t i o n b yinterchanging the eyepiece with that of a different focal length.

A diameter of an objective lens or primary mirror is called an effective aperture(aperture).
A focal length is the distance from the center of an objective lens or primary mirror
to the point (focal point) where refracted or reflected light converges.

Focal Ratio = �Focal Length divided by Aperture
Brightness with a focal ratio is expressed by an F value. The smaller the value, thebrighter the image delivered by an astronomical telescope.

For viewing widely scattered star clusters or nebulae,
lower magnifications between 20x and 50x are suitable.
For double stars and surfaces of the moon, middle
magnifications from 50x to 100x would work well. To geta good look at planets, higher magnifications will be
required.
EyepiecesF o c a l L e n g t h o f Te l e s c o p e i n/ Focal Length of Eyepiece

Typically, a focal length of the eyepiece is on theside of the eyepiece barrel. Example: The

Example: The eyepiece of

4 Magnification appropriate to your Telescope
Although it is possible to increase magnification excessively, it
results in a dim image and narrow field of view. You need to set
up magnification appropriate to your astronomical telescope,and the aperture of the telescope will determine it. How muchmagnification is too much, and how much is just right?
Multiplying the telescope aperture millimeters by 2 will get amaximum effective magnification.

80mm in aperture

80×2＝160
An 80mm telescope canoperate at a maximum of

A 100mm telescope canoperate at a maximum of
200x theoretically.

M o s t o f t h e s e o b j e c t s a resuitable to view withmagnification lower than 50x.
For the Andromeda Galaxy andOrion Nebula, magnification of
20x to 30x is recommended.

Many intriguing deep sky objects,
variable stars, and comets can beobserved with a small telescope
if they are not too dim in the fieldof view of your telescope.

Never look directly at the sun
with the telescope. Use a
refractor and a proper sun
projection screen for observing
the sun safely.

Magnification is not the only factor!

Image quality in different apertures

Telescope magnification can be increased to any high magnification
theoretically, however, it does not necessarily make the image clear. It
is essential to view at an appropriate magnification. An immoderately
high magnification deteriorates image quality and will result in a blurred
image.�High Magnification Does Not Imply High Performance.
It is said that the allowable maximum magnification is 2.5 times theeffective aperture of the telescope.
For example, if your telescope has 80mm in aperture, the usable
maximum magnification is 80x2.5 = 200.

The larger the effective aperture of the telescopes, the higher the lightgathering power and resolving power of the telescopes. Even though
the image quality is dominated by the optical performance of theobjective lens or primary mirror, telescopes with large aperture yield abright and high contrast image.

Appropriate magnification

Large aperture at high magnification

Excessive magnification

Small aperture at high magnification

Generally, flashlights are designed mainly for brightness. If
you use it in astronomical observing sessions, the bright light
gives strong stimulation to the eye and this affects your nightvision. As a result, stars become hard to see for a shortwhile. Our first Astro LED lamp SG-L01, in which a red color
lamp was incorporated, was a solution to this problem. Butt h e r a n g e o f t h e v i s i b l e l i g h t i n re d i s n a r ro w a n d n o tnecessarily good at visibility. With our Astro LED lamp

Optical Tube Assembly

There are three types of optical tubes; refractor,
reflector and catadioptric which is an advanced
combination of the refractor and reflector. The
optical tube is attached to a Vixen mount with adovetail plate system which simplified theattachment and removal of optical tubes.

Finder Scope

A finder scope which is subsidiary
to the main optical tube makes it
easier to place a target object into
the telescope's field of view
because of its low magnification
and wider field of view.

AsWith Vixen equatorial mounts, you have a wide selection of
Vixen telescopes and optical tubes, including refractors,
reflectors and catadioptric systems, from which to choose.
You are sure to find one to fit your specific observing needs.
You can also start with a smaller telescope and upgrade
later to a larger one as your interest and needs grow. All
Vixen products are interchangeable. The Vixen equatorial
mounts are an excellent choice for anyone who wants tostart exploring the night sky with a truly reliable instrument.

A About Torque LoadlVixen uses terms of Torque Load as guidance for an allowableloading weight. The torque load can be calculated by thefollowing formula.

Half Pillar

Torque Load (kg-cm)= Weight of an instrument loaded (Kg) x Distance fromthe place where the RA and Dec axes cross to thecenter of gravity of an instrument loaded (cm) n

It facilitates observing in
culmination and avoids
hitting the long telescopetube to the tripod leg.

[Example] When you install an AX103S optical tube assembly on the
SX2 mount using the dovetail-plate mounting block, thetorque load is calculated as follows:

Equatorial Mount

A wide variety of Vixen
eyepieces is listed on
page 52 to make yourenjoyment of celestial
observation.

1) You find the outside diameter of the AX103S is 115mm
from the specifications on page 44. Supposed that thecenter of gravity of the AX103S is the center of the opticaltube assembly, it would be a point of a half of the opticaltube diameter. It is about 6cm here to make a calculationeasier.
2) The space of the tube ring and dovetail-plate mounting
block is about 4cm in breadth in total.

TripodThere are four types of durable tripodsthat are available for AP, SX series, AXJ or
AXD2 mount. Robust permanent pillars
are available for SX series, AXJ or AXD2.

3) Distance from the RA and DEC axes cross point to themount head of the SX2 is about 10cm. s[Calculation] 6.4 kg x (6cm + 4cm + 9cm) = 121.6 kg-cm

AP Equatorial Mount
Easy to Use Versatile Mount. Customize to Fit your Observing Style.
The AP mount is not only suited for beginners who want to become
familiar with equatorial mounts, but also for experienced observers
who want a simple grab-and-go mount. The AP mount consists ofseveral modules that are joined to make a highly portable German
equatorial mount of excellent quality. With the available R.A. motor
module complete with the STAR BOOK ONE controller, you canachieve accurate tracking of celestial objects. The AP mount is agood choice for starting the first step to serious celestial observing.
（AP Mount）

There are two basic versions of the AP mount from which to choose.
AP: The basic AP comes equipped with the manual slow-motion control inboth the R.A and DEC. With its friction control mechanism, you can point
the AP mount quickly to your target object.
AP-SM: It employs the R.A. motor module and STAR BOOK ONE handcontroller for tracking celestial objects automatically. The upgrading will becompleted with an addition of an optionally available DEC motor module.

SXD2 Equatorial Mount WL
The Next level of Performance.

Increase Load Capacity
Materials and manufacturing processes have been revised toenhance the rigidity and precision of the original SX Mount.
Both the R.A. and DEC rotation axes of the SXD2WL are madeof thick steel with brass wheel gears, critical to accurate
movement of the Mount. These changes have increased theprecision of the Mount.

Smooth Motion with Bearings
Bearing are used in the
R.A. and DEC axes andthe rotating shafts of theworm gears. This reduces the load on the motors
and ensures smooth rotation. Lapping of both
worm gears and worm
wheels ensures smooth
operation.

SX2

SXD2

Equatorial Mount

Pulse Motors and Micro-Step Motion Control
The heart of the SDX2WL is the precision pulse motors.
These highly responsive motors
have a micro-step motion control
system to deliver powerful, yet
s i l k y s m o o t h d r i v e c o n t ro l s i nboth fine motion and quick
slewing.

Polar Alignment Scope PF-LII
A polar alignment scope is essential for taking longer
exposure astrophotography. The SDX2WL comes as standard
with the polar scope PF-LII, which features easy and accurate
polar alignment as you bring Polaris and two other stars into
designated positions on the reticle in polar scope's field ofview. A free app called PF-L Assist for smartphones andtablets will help you bring Polaris and the other two stars in
the field of view to thec u r re n t d i re c t i o n s e e n i nyour observing site.

Low Power Consumption
The electricity consumption is reduced by 20% as comparedto the STAR BOOK TEN controller with a visual screen display(Factory default settings). It is an advantage for hours ofcelestial observation or astrophotography.

Controlling the Telescope by Swiping the Screen
Pointing the telescope to your celestial target
is easy with a swiping motion. The telescopemoves in the same direction as you swipe thestar chart on the screen of your smartphone.
Examples of the Celestial Navigation Screens

Celestial GO-TO Navigation with a Smartphone
On installing a dedicated app “STAR BOOK Wireless” to yoursmartphone, you will make good use of various menus
prepared for celestial navigation including an automatic
GO-TO function.

No Tangled Cables

Celestial GO-TO Navigation
While looking at the star chart screen ofyour smartphone, you tap a target
object you want to observe. The
telescope will lead the object into thefield of view of the eyepiece and starts
tracking it.

Equatorial Mount

Attaching the Wireless Unit to the mount will enable you tooperate your telescope via Wi-Fi using a smartphone or a PC
tablet comfortably. No cables are required that are likely to
be tangled during operation.

It is essential to download the app STAR BOOK Wireless toyour smartphone for using the Wireless Unit.

High-Speed Response
Troubles typically seen with the wireless connection aredelays in motion against response. We successfully reduced
this shortcoming to the level of a cable connection. You will
enjoy stress-free operation with smooth responses.

The SXP2 and AXD2 mounts come as standard with a user-friendly STAR BOOK TEN
controller that features a large LCD screen and intuitive operation by command keys.

With observatory-quality precision controls, your target
object appears on the high definition screen of the STARB O O K T E N a n d i n y o u r t e l e s c o p e ’s f i e l d o f v i e w
instantaneously. The night vision mode illuminates thewhole screen in red, if applied, and will limit the brightness
to the observer’s eyes. Zooming in and out of the star chart
is interlocked with motor speed. With the STAR BOOK TEN,
a bulky PC is not needed.

SXP2 Equatorial Mount
The pinnacle of the Vixen SX series mounts has been re-designed for increased performance.
Combining the best functions of the SX series of mounts and the STAR BOOKTEN controller, the Sphinx Professional is designed for high-performanceobserving and astrophotography.
Pedestal with Robust Fork Arms Design
The fork arms construction that brings high stability is thesame as the upper-class AXJ mount. With this feature, thesturdiness of the compact and handy equatorial mount has
been increased further with the SXP2.

SXP2 Mount

Equatorial Mount

Speciﬁcations

Belt Drive System

R.A. slow motion

In the conventional drive system of the Vixen equatorial
mounts, the power of the motors is transferred to the worm
gears by the gear trains. The gear trains require a minimum
amount of play to rotate gears because play gains as thenumber of gears increases. To avoid such demerits, wechanged the transmission power by the motors from the gear
train to a belt system. We eliminated the backlash originatingfrom the gear trains and reduced gear noise dramatically.
Quiet and stable motion with reliable response has been aresult.

DEC slow motion

Precise Tracking with P-PEC

Motor drive

Every movable part of the SXP2 mount has a design toproduce highly smooth movements. Besides, the periodic
error corrections provided by the STAR BOOK TEN rectify anirregular motion of the tracking gear wheels. The advanced
P-PEC (permanent periodic error correction) employed with
the SXP2 allows you to save the records of your rectification.
When you power the SXP2 off, the corrected tracking errors
are stored. When you tur n it on again, the recorded
corrections can read out to keep the celestial tracking of alevel higher next time.

Advanced Motor Layout
As seen in our SX series of the equatorial mounts, heavy R.A.
and DEC motors are set in the lower part of the declination
body. The advantage is you may need fewer counterweights
as the center of balance of the SXP2 comes below thecrossing point of the R.A. and DEC axes.

Flat Mount Head
The top of the round mount head, 35mm in diameter, features
eight M8 with pitch 1.25mm thread holes. These holes arearranged at 45 degrees intervals for attachment of different
optical tubes. The Vixen dovetail tube plate or dovetail bar is
attachable using an optical dovetail-plate mounting block.

The AXJ Mount features superior performance for the discriminating
astrophotographer.
Vixen’s new design introduces the sturdy and precision-made AXJ mountis designed with a belt drive to eliminate backlash and gear noise. It isbest suited for the demanding astrophotographer as a comfortable andsecure imaging platform.
Superior Periodic Error Correction V-PEC
The periodic motion of each mount measured andcorrected in advance is stored on the nonvolatilememory inside the AXJ mount. The periodic
motions in 12 points are checked on the worm
wheel at an angle of 30 degrees each by using ahigh-resolution periodical motion measuring tool.
The most effective correction has been calculated
based on this inspection.
Vixen’s permanent periodic error corrections called
the VPEC work automatically when you use theA X J m o u n t . I t p ro v i d e s p re c i s e t r a c k i n g a s
accurate as +/- 4 arc seconds or less. You canprogress the tracking accuracy further by adding
your own recorded PEC as the occasion demands.

Belt Drive Systemchanged from the gears to a belt system. As aresult, backlash
originating from thegear train has been
eliminated and gear
noise has been
dramatically reduced.
Quiet and stablemotion with reliable
response has beenachieved.

Equatorial Mount

In the conventional drive system of the Vixen
equatorial mounts, motion power of the motor wasconveyed to the worm gear by the gear trains. The
gear trains require a minimum amount of play tomove the gears and the amount of play gains as
the number of gears increases. To avoid this, thetransmission of the motion power has been

Equatorial Mount

Comfortable ‘Go-To’ Manual Slewing

In general, astronomical navigation isestablished by electrically matching thec o o rd i n a t e i n f o r m a t i o n s t o re d i n t h ememory of the controller with the
motor-rotation angle of the equatorial
mount and mechanically matching theorientation of the telescope tube with the
motor-rotation angles at the same time.
For this reason, as long as you use thefunctions for automatic navigations, are l a t i o n b e t w e e n t h e o r i e n t a t i o n o f a n o p t i c a l t u b e a n d t h emechanical position of the motor-rotating angles must be kept
constantly. You are not allowed to unfasten the clamps on theequatorial mount to move the telescope's optical tube manually inany direction.
Therefore, if you can match the telescope’s orientation with the
motor’s rotating angles both electrically and mechanically, positions
between the telescope and the coordinate on the controller will
always correspond even if you unfasten the clamp levers. The AXJ
encoders make that possible.

The encoders monitor the tracking of the AXJ equatorial mount withhigh accuracy of 0.1 arc second (R.A.) per resolution. The diagram
shown is a comparison of the periodic motions of the AXJ without
the encoders and the AXJ equipped with the encoders. The AXJ
encoders detect the slightest amount of periodic motions* 1 that areremaining in the AXJ renowned for its high precision tracking andrealize even a higher precise tracking as a result.

The AXD2 has consciousness with the design for the era of digitalization.
With its surprising precision, incredible performance, and simplicity of use, it has no rival in its class.

Sturdy R.A. and DEC axes but Lightweight Body

High Response Pulse Motors

The structures of German equatorial mounts have beenthoroughly examined to create the sturdy but lightweight
AXD2 Mount. The A7075 super-alloy, the strongest among
the group of aluminum alloys, is chosen as the material for
the R.A. and DEC axes. The tensionof the A7075 super alloy is said to bestronger than titaniumfeaturing lightweight and highstrength, even though its
specific gravity is 38% lessthan titanium. Both axes areas thick as 50mm in diameter.
The A7075 super-alloy used
for the axes has made the
AXD2 lightweight while
retaining its sturdiness.

Vi x e n s e l e c t e d t w o - p h a s e h y b r i d p u l e s m o t o r s o f h i g hperformance for the AXD2 to achieve quick responses andsilk-smooth movements. An excellent micro-step motion
control system yields a wide dynamic range to the pulse
motors. The AXD2 fruits surprisingly ultra-smooth drivingfrom tracking speed to slewing speed 800x of the sidereal
rate at a maximum. The micro-step motion controls with high400 pulses per second will result in movements free of
unstable behaviors. A newly developed software program andimprovement of the motor control board successfully reduce
the electricity consumption of the pulse motors while
maintaining high torque.

R.A. Shaft (Polar Axis)

DEC Shaft

The sizes of the worm wheels increase in the AXD design
compared to our former-flagship New ATLUX mount. The
AXD2 mount has 270 teeth in R.A. and 216 teeth in DEC. It
achieves a high level of tracking accuracy and tracking
stability.

Ultimate Periodic Error Correction – VPEC
The periodic motion of each AXD2 mount is pre-measured
precisely and stored in the nonvolatile memory inside themount unit at Vixen’s factory. It is called V-PEC. The V-PEC
works in automatic as you start using the mount for tracking.
It provides tracking as accurate as +/- 2.8 arc seconds. You
can upgrade the tracking accuracy further by adding yourown recorded PEC as the occasion demands.

Highly Comfortable Operation

The AXD2 Mount – Innovative, Elegant and Functional.
The AXD2 mount has minimal external protrusions and an innovative interior design.
It is the flagship of Vixen’s line of well-designed equatorial mounts.

Elegant Sliver Setting Circles
Polished silver anodized setting circles in R.A. and DEC haveboth beauty and utility. They not only match the white AXD2
body nicely but also allow you to point your telescope to atarget well within the provided verniers. The R.A. reads one
minute (hour angle), and the DEC reads ten arc minutes (orabout 0.167 degrees).

Advanced Motor Layout

Reliable Wiring
All the electronic parts inside the AXD2
mount are accumulated on one electric
circuit board to simplify electrical wiring.

The electrical circuit board equipped ishighly reliable and safe.

Polar Alignment Scope
The Polar Scope is to accurately align the AXD2 mount to thenorth or south celestial pole. The polar alignment is easy.
You bring Polaris and two other stars into the polar scope’s
field of view and match them with the designated position ont h e s c a l e o n t h e p o l a r s c o p e ’s re t i c l e ( i n t h e n o r t h e r nhemisphere).
The brightness adjustment dial of the polar scope will
illuminate the reticle in red when turned on. Brightness isadjusted in 8 steps. The red light gradually dims after a given
interval of time and turns off automatically.

Reticle36

The heavy R.A. and DEC motor units are placed in the lower
part of the declination body so that the center of balance of
the AXD2 mount shifts to below the crossing point of the R.A.
and DEC axes. It makes the lower portion of the declinationbody act as a counterweight. Additionally, the low-profile
mount head allows the mount to balance with lesscounterweight.

Flat Mount Head
The mount head of the AXD2
mount is an anodized
aluminum plate that is highly
resistant to scratches. The
threaded holes on the mounthead accept Vixen’s dovetailmounting block and othermanufacturer’s tube plates as
well.

Star-Scape Photography and Wide-Field Astrophotography
Taking pinpoint images of stars is simple by using a camera
equipped with a wide field photographic lens. Generally, there
are two types of astrophotography in which a telescope’s opticaltube is not necessary. Taking constellations and the Milky Way in
combination with scenery is called Star-Scape photography.
Taking only celestial objects is called Wide-Field
astrophotography. You will need a camera attached to apolar-aligned equatorial mount or star tracker to reduce startrails.

Star-Scape Photography
Photographs of landscape or architectural objects,
a c c o m p a n i e d b y c o n s t e l l a t i o n s a n d t h e M i l k y Wa y, a reexamples of this type of photography. Adding landscape orarchitectural objects in the foreground may make your photos
more impressive.

Astrophotography

What we Recommend: POLARIE U and POLARIE star
trackers allow you to create ‘star-scape’ photos in night-sky
scenes by adding an almost motionless night landscape orsilhouetted figure in the foreground of your frame.

Orion Ascending Photo by Akio Nakanishi
Taken with POLARIE (Star-scape mode)
Camera: Canon EOS 60D, at ISO1600, 15-minute exposure

Mist to autumn (In Autumn mist air)Photo by Kouji Ohnishi
Taken with POLARIE (Star tracking mode)
Camera: Canon EOS 5D Mark II
at ISO2500, 30-minute exposure［Fixed-Tripod Imaging］

When shooting a starry night sky with a camera
fixed on a tripod, if an exposure time is longer,
the stars will not appear as dots but appear aslines. This is because the stars appear to move
due to the diurnal motion of the stars (rotation of
the Earth).

Wide Field Astrophotography

Time-Lapse Imaging

U s u a l l y, n i g h t s c a p e s a re n o t i n c l u d e d i n t h e f r a m e s o f
photographs, or they will be in the background part of yourimage.

The time-lapse astrophotography is video imaging, made of hundreds
or thousands of still images of the starry skies taken at regularintervals. It allows you to capture the motion of constellations and theMilky Way impressively with the passage of time in the foreground of
silhouetted terrestrial objects. 。

What we Recommend: It is essential to use an equatorial
mount or AP star tracker (or POLARIE / POLARIE U with polaralignment scope) to eliminate trails of stars caused by theearth’s rotation.

38

What we Recommend: A POLARIE U is highly recommended

Taking pinpoint images of stars is simple by usinga camera equipped with a wide field photographic
lens. Generally, there are two types ofastrophotography in which a telescope’s opticaltube is not necessary. Taking constellations andthe Milky Way in combination with scenery iscalled Star-Scape photography. Taking only
celestial objects is called Wide-Field
astrophotography. You will need a camera
attached to a polar-aligned equatorial mount orstar tracker to reduce star trails.
What you need:

Astronomical Telescope: An alt-azimuth
mount with slow motion control works
well for shooting the moon and brightplanets.
S m a r t p h o n e C a m e r a A d a p t e r : Yo u
simply place your smartphone attached toa dedicated camera adapter in tandemwith the visual back of your astronomical
telescope.

The prime focus photography technique uses a camera body, or a CCD/ CMOS imaging camera attached withadapters to an optical tube. Neither an eyepiece nor a camera lens is required. Eyepiece projection photography isa method for taking images of a magnified object through an eyepiece inserted between the optical tube and a
DSLR camera body or a CCD/ CMOS imaging camera.

Prime Focus Photography

Eyepiece Projection Photography

Prime focus photography is a typicalmethod of photographing nebulae or starclusters. It employs a DSLR (Digital Single
Lens Reflex) camera directly attached tothe astronomical telescope. Particularly, it
is a method of astrophotography in which
you replace the telephoto lens with the optical tube of theastronomical telescope. It enables photography with a highmagnification at a reasonable cost compared to a dedicatedtelephoto lens for the DSLR camera. When you takephotographs of deep-sky objects with the prime focus
photography method, it is necessary to track a celestial object
for a long time. It may sound a little complex, but you can try
this method by referring to articles on astrophotography.

Eyepiece projection photography isemployed when you take photographs ofthe moon’s surface or planets. Unlike
prime focus photography in which only thetelescope optical tube is used, theeyepiece is added to magnify images oft h e o b j e c t s e a rc h i n g f o r d e t a i l s . T h e
images taken with this technique appear
larger than those taken with the prime
focus.

What we Recommend: An equatorial
mount such as AP, SX2WL, SXD2WL,
SXP2, AXJ, or AXD2 is recommended.
Long exposure is required for capturing
faint objects like nebulae and starclusters. Thus, the use of a sturdy mountwith a motor drive for autoguiding isessential.

PORARIE U
It enables you to capture the starry sky as a piece of scenery and leave the beauty of the night sky
as a photo of the landscape above the earth, the universe.
The POLARIE U extends the world of star-scape photography, and everyone canexperience real enjoyment of shooting the starry sky. It is a lightweight, compact,
motor-driven mount for your camera that moves according to the movement ofstars. By moving the camera according to the diurnal motion of the celestial
object, it accomplishes not only conventional photography with pin-point stars
through tacking and long exposure but also offers interval and time-lapse
photography by remote control via a smartphone.
Five tracking modes
Star-scape photography (Half speed of thesidereal rate) mode… If this model is chosen,
the POLARIE U tracks stars at half the speedof the diurnal motion of the stars. The
terrestrial objects are moved less ascompared with images taken by wide-field
astrophotography at a given exposure time.
Wide-ﬁeld astrophotography (Sidereal rate) mode… If this model is chosen, thePOLARIE U follows stars at the same seed as the diurnal motion of the stars. It is
suitable for capturing constellations, the Milky Way, or faint celestial objects such as
nebulae and star clusters.
Solar tracking mode… Useful for shooting spectacular pictures of a solar eclipse.
Lunar tracking mode… Useful for shooting the Moon.

Astrophotography

Custom mode… It allows for setting the POLARIE U to your desired tracking speed.
The initial setting is four times of the sidereal rate. If you change the settings for adifferent speed, a smartphone or other wireless device and application software are
required.

Shutter release terminal and Autoguider port

With the use of a camera that is equipped with a bulb shutter
function, the shutter release terminal allows for the control and settingof interval photography. The shutter
release control in conjunction withthe motion of the POLARIE U allows
for setting up a time-lapse sequencewith ease via a smartphone. An
autoguider port for a commerciallyavailable autoguider is provided. (inthe direction of R.A. only).

Applicable to tripods with the 3/8” and 1/4” camera screws

The sockets for the 3/8” camera screw are provided. A supplied 1/4”
convert screw adapter makes the POLARIE U available for tripods
with the 1/4" camera screw also.

The smartphone camera adapter is usable for telescopes,
spotting scopes, and microscopes if the eyepiece barrels are
adaptable to it in diameter. Be sure to priory check the
conformity to your smartphone with a table of figures below.
Eyepiece Barrel Size
It is designed to pinch the barrel of the visual back or eyepiece
having a grip of 19mm to 53mm in outer diameter and over
20mm in height.

Width: 58-110mm(2.29-4.33 inch)

Astrophotography

When you apply a smartphone for taking photography using itwith an astronomical telescope or spotting scope, you need to
set the smartphone to come closest to the eyepiece of that
scope. It would be very difficult to keep aligning to the opticalaxis of that scope by holding the smartphone stably, for such
purposes. The smartphone camera adapter makes it easy.
You simply adjust the position of the camera lens on thesmartphone mounted on the smartphone camera adapter to an
image on the eyepiece caught by the astronomical telescopeor spotting scope.

Auto-guiding
System,SoftwareIf you take photos of faint deep sky objects such as nebulaewith a telescope and a DSLR camera (Prime focus
astrophotography), you often need to apply long exposure
times. The longer the focal length of the telescope, the larger
the atmospheric refraction of stars appears. This affects theaccurate tracking of your mount. Mechanically inherent
periodic motions of the mount may further influence thetracking that precisely follows a guide star's diurnal motion.
The auto-guiding offers perfect tracking by a system shownon the above as an example. A CMOS or CCD auto-guiding
camera attached to the guide scope keeps the guide star inview to achieve accurate tracking. The auto-guiding is moreconvenient and less fatiguing for the astrophotographer.

SD Apochromatic Refractors
The SD lenses focus visible rays of light from the C-ray (red),
d-ray (yellow), e-ray (green), and F-ray (blue) to g-ray (purple)at nearly the very same position, as compared with ourprevious models, as shown in the diagrams of sphericalaberration below.
It verifies that the chromatic aberration is corrected at a highlevel over a broad spectrum of light with the SD lenses.
E s p e c i a l l y t h e g - r a y, w h i c h a ff e c t s i m a g e c o n t r a s t , i sdepressed excellently.

SD81SII, SD103SII, SD115SIIThe SD glass produces clear and high-contrast image viewing,virtually free of false color. The design uses newly developed
environmentally friendly glass technology. Brighter F7.7 images
will satisfy the most demanding visual astronomer orastrophotographer.
The optical tubes are very compact and lightweight. That helps inhandling the optical tube without inconvenience when you carryand set up the telescope. You have less counterweight to balance
the telescope, also. It comes with a carry handle.

Quad Element Design
Vixen AX103S features a three-element objective lens, incorporating
an SD lens in the center of an air-spaced triplet lens system and thefourth lens inside the focuser drawtube. The ‘Apo Maximum’ lenselements are laid in the precision machining cells to exhibit superb
optical performance. The advanced design produces crystal-clear,sharp, and high-contrast images with no trace of false color.

Objective lens

Below is a comparison of spherical aberration between the AX103S
and Vixen’s FL102S Fluorite telescope, which was renowned as amasterpiece for its excellent color correction. The diagram shows
how the AX103S outperforms the fluorite optics. The bundle oflight rays (spectrum) on the AX103S is straighter than on the
FL102S. The result is that residual chromatic aberrations are
reduced far below the threshold of visibility.

We use Lanthanum glass in our SLV eyepieces to materialize high-quality, comfortable
eyepieces with the superior optical performance. With the advantage of theextraordinarily high dispersion rate of Lanthanum glasses, the SLV eyepieces yieldbright and sharp images to the very edge of a field of view.
So-called “ED” glass is widely known as a high-quality lens element, bur Lanthanum
glass featuring high dispersion rates cannot be compared simply to ED glass having
low dispersion rates. The application of Lanthanum glasses to the optical design
reduces the lens elements, improves light transmission, and results in brighter
images. Besides, with the SLV eyepieces, image distortions are successfully reduced
to the edge, and both coma aberration and astigmatism are depressed invisibly.�That
makes the SLV eyepieces compact, lightweight, and easy to handle.
The apparent field of view of the SLV eyepieces is determined to be a moderate 50
degrees to prevent fatigue or stress to the observer’s eyes. Eye fatigue may occur
when using an eyepiece with an ultra-wide field of view over 85 degrees. We believethat such a wide but unstable viewing field is beside the point of “comfortable”
viewing. An advantage of the moderate 50 degrees field of view with comfortable
20mm long eye relief will help observers to concentrate on a target object.

Tripods
About the Unification of the Connection Specifications
between Mounts and Tripods
Historically, Vixen GP Mounts and Sphinx Mounts haveused different tripods. In March 2011, Vixen unified theconnectivity of tripods and created an SXG tripod to fit allof these mounts. You With this modification, one single
tripod is used for different types of mounts such as the GP
equatorial and HF2 altazimuth fork mounts.
The mounting base of the GP2/GPD2 mounts which ﬁts the tripod head of the SXG
tripod was changed from 60mm to 45mm in diameter. The peg on the tripod head of
the SXG tripod can be positioned in place according to the mount types used.
