Ethos-SX 3.7- & 4.7mm 110° Eyepieces
Thank you for purchasing this ETHOS-SX eyepiece. We wish you years of exciting viewing andwe welcome comments on your personal experiences.
ETHOS-SX110 ° apparent field models fits both 2” and 1¼” focusers or diagonals.
Designed as a 1¼” eyepiece, there is NO optical benefit when using a 2” barrel. The 2” barrel
adapter is included just for convenience, but it is also threaded to accept our 48mm filters.
For 1¼” holders
Just unscrew the 2” adapter.
In this mode, the eyepiece will be parfocal with Tele Vue’s Plössls, Type 6 Naglers, Nagler Zooms,
and 1¼” Panoptics.
For 2” holders
Just use the 2” adapter: screw it on until it stops. Do not tighten.
In this mode, the eyepiece will be parfocal with the 10- and 13mm ETHOS.
Paracorr Coma Corrector
This eyepiece is very well corrected over the full field. For Newtonians/Dobsonians f/4 or faster,
we recommend our Paracorr coma corrector to eliminate mirror coma. This permits the same kindof full field sharpness routinely seen in Tele Vue’s NP-Series refractors. See your Paracorr instruction
sheet for proper setting.
DIOPTRX™
If you have eyesight astigmatism, you can add Tele Vue’s Dioptrx™ Astigmatism Corrector to
ETHOS, instead of using eyeglasses, to get the sharpest view possible. However, unless you havesubstantial astigmatism such as 2 diopters, and a fast scope, such as f/4, you are not likely toneed Dioptrx™ with this short focal length eyepiece.

Ethos SX 110° Simulator eXperience Eyepieces
Al Nagler eagerly pushed Ethos designer Paul Dellechiaie to extend the Ethos-SX focal lengths to reach110°, the same field as the LEM Simulator optics Al designed to train NASA astronauts for lunar landings(see below). Years after the LEM program, the memory of the 110° view of the simulated lunar surface
moving through the triangular cabin window of the LEM inspired Al to develop an “Ultra Wide Angle” (hispatent title) telescope eyepiece to approach that “simulator experience.” When the 82° Nagler eyepiece
hit the observing fields, it changed how amateur astronomers viewed the heavens. An early customer
dubbed it a “spacewalk” view.
Essentially, “the experience” is about creating an image as natural as one sees with the unaided eye.
With Paul’s help, Al’s initial dream for amateur astronomers is now fully realized. The Ethos-SX eyepieces
are designed and crafted to combine exceedingly wide field of view with all the contrast, color-rendition,
distortion correction and center-to-edge sharpness needed to achieve that natural view.
Beyond the desire to simply achieve 110° for an extended deep sky field (21% more AFOV area than100°) the Ethos-SX are superb planetary eyepieces. The 3.7mm permits a nice 62% power increase
from a 6mm Ethos, while retaining 68% of its TFOV. The 3.7mm actually has more TFOV than our 8mm
Plössl and 5mm Nagler Type-6! The 4.7mm rests midway between the 3.7mm and 6mm focal lengths.
Compared to the 3.7mm, its lower power and 60% greater field area extends the SX-110° technology
to more telescope applications than ever before.
We don’t think we can aptly describe Al’s original experience of “flying over the moon,” but YOU can
now experience what the astronauts saw decades ago.
Apollo Lunar Excursion Module (LEM) Simulator
Seen at left is one of the Infinity Display Projectorsthat fit over the LEM simulator. A separate unit
was required for each window of the spacecraft.
You can imagine why the astronauts affectionately
dubbed the full collection of simulators for the
Apollo mission “The Great Train Wreck!”
The optical design consisted of a series of sixfoot mirrors, beam splitters, and a three-foot lens.
It took a televised image of the lunar surface
along with a separate background star field andprojected the combined image to infinity. Withthe triangular compressor lens (seen at left) placed
against the triangular window of the simulated
LEM cabin, the astronauts saw star fields or
the Moon filling the LEM window. The Infinity
Display Projectors essentially acted as giant 110º
eyepieces, each with a 12” exit pupil and 12”
eye-relief. So, at one-foot from the window, theastronauts saw a 110º field of view.
And, you thought Ethos-SX eyepieces were big.
Imagine that hanging off your telescope!

This Eyepiece Accepts FONEMATE

If you need a convenient way to take still, video, or timelapse images through an eyepiece, use our FoneMate™
smartphone adapter. It securely clamps to compatible Tele Vue eyepieces. Smartphones as
big as the Galaxy Note 4 can be fitted to the FoneMate™.
Enter bit.ly/TVOPTFM in browser URL bar for more info.

EBX-21202” EYEPIECE BARREL EXTENDER

Some of our eyepieces have dual 2" / 1¼" barrels which make it impossible to use 2" filters due to the 1¼" barrel
extending below the 2" barrel. The 2" Eyepiece Barrel Extender adds 1.2-inches to the 2" barrel toprovide a mounting location for 2" (48mm) eyepiece filters. It also increases backfocus distance andan also help parfocalize eyepiece sets.
Enter bit.ly/TVOPEBX in browser URL bar for more info.

This Eyepiece Accepts BANDMATE™ Filters
Adding Bandmate filters to your eyepiece make nebulae "pop-out" in the field. Bandmate does this by passing selectwavelengths of light and blocking other to darken the sky and increase contrast. Several filters areavailable for 2" and 1¼" barrel eyepieces.
• Bandmate Nebustar is a a unique narrowband filter design specifically for Tele Vue as a generalpurpose nebula filter for scopes of any size. Unlike other ultra-high constrast (UHC) designs,
Nebustar blocks red wavelengths normally passed by typical UHC filters. The design eliminatesstar bloat to produce sharper, more natural looking stars along with enhanced nebulosity.
• Bandmate OIII filter enhances planetary nebulae and supernovae remnants.
• Bandmate Hβ brings out the hydrogen-beta emission lines found in hydrogen emitting nebulae.

VISUAL-IMAGING PARACORR TYPE-2

Newtonian/Dobsonian telescopes can benefit from using a Tele Vue Paracorr (Parabola Corrector) to eliminate coma in theimage. Coma is the effect that makes off-center stars appear like little comets (it becomes more apparent as stars
move closer to the edge of the field). While a Newtonian/Dobsonian telescope will benefit from the use of Paracorr, those faster than f/5.0 will see the greatest results. Stars at the edge of the field will improve so dramatically, that when using top-notch Tele Vue eyepieces an object will be equally sharp anywhere in thefield. It also prevents faint stars from disappearing at the edge of the eyepiece field. This is not only aesthetically pleasing, but it also greatly reduces the need to constantly nudge the scope to keep the object
centered in the “sweet spot.” Just insert Paracorr into your 2" focuser like a 2" Barlow (it has a 15% [1.15x]
magnification factor) and add Tele Vue eyepieces to suit your needs. It’s a recipe for perfection whencombined with Tele Vue eyepieces.
The Paracorr Type-2 allows an f/3 parabolic mirror to perform like an f/12 without it. This permits
development of a new generation of larger ladderless Dobs, with bigger, sharper fields than ever before.
Indeed, it's already been successfully applied by Mike Lockwood to his 20" f/3 and 14.5" f/2.55!
This model Paracorr is dual function: the tunable top permits positioning all Tele Vue eyepieces for
optimum performance (see eyepiece position chart on the other side), and the optical assembly can beremoved for use in an imaging system with DSLR or CCD cameras along with Tele Vue Imaging System accessories.

Choosing Your Eyepieces

by Al Nagler
CEO, Tele Vue Optics, Inc

MAGNIFICATION

Eyepieces determine your telescope’s magnification.
Magnification = telescope focal length ÷ eyepiece focal length
TRUE FIELD OF VIEW

Eyepieces also determine the true field you see in the sky. To calculate the true field of view that you will see (in degrees):
True field of view = (eyepiece field stop diameter ÷ telescope focal length) x 57.3
THE FIELD STOP AND APPARENT FIELD OF VIEW

The field stop is the metal ring inside the eyepiece barrel that limits the field size. It’s projected by the eyepiece so that it appears
as a circle out in space when you look through the eyepiece. The angular diameter of this circle is called the apparent field of view
(AFOV) and is a fixed property for each eyepiece design. For example, Plössl and Nagler Zoom eyepieces have an AFOV of 50º,
Panoptics have 68º, Delos have 72º, Naglers have 82º, Ethos have 100º and the Ethos-SX eyepiece has 110º.
LOW-TO-MEDIUM POWER VIEWING

For low-power viewing of large objects, or to use your telescope as a low-power finder, use an eyepiece that delivers close to the
maximum possible true field of view (note that for 1.25" eyepieces, the maximum field stop diameter is 27mm; for 2" eyepieces, it’s46mm). Then add eyepieces covering uniform increments in smaller field stops. For example, if your widest field eyepiece has a
40mm diameter field stop and you choose a decreasing increment diameter factor of 2 (which results in a 4x decrease in area size),
you’ll end up with eyepieces having field stop diameters of approximately 40mm, 20mm and 10mm. To further fill in withincremental steps, add eyepieces with approximate field stop diameters of 28mm and 14mm. Of course, avoid duplicating focal
lengths. For example, if you use a 31mm Nagler (with a 42mm field stop diameter), you would not need a 32mm Plössl (with a
27mm field stop diameter).
In general, for each field stop size, choosing eyepieces with shorter focal lengths and larger apparent fields of view will allow you to
see more detail and fainter stars. In addition, you’ll have a smaller exit pupil to better match your eyesight.
EYEGLASSES AND EYE RELIEF

If you do not need eyeglasses to correct astigmatism, don’t use them when observing. If you wear
glasses to correct astigmatism, make sure they’re multi-coated, and try to choose eyepieces thathave at least 15mm to 20mm of eye relief, to minimize any field reduction (vignetting). However,
you will find that with small exit pupils such as 1mm or less, you probably will not need eyeglasses,
and can therefore use eyepieces with less eye relief. You can use DIOPTRX instead of eyeglasses
for best performance, with Tele Vue eyepieces that accept this accessory.
EXIT PUPIL

The exit pupil is the image of the objective that is formed by the eyepiece. It’s where you place youreye to see the full field of view.
Exit pupil = eyepiece focal length ÷ telescope f/#
For reflecting telescopes, it’s best to avoid exit pupils larger than 7mm or smaller than 0.5mm. Refracting telescopes have no upper
limits on exit pupil sizes.
IMAGE AMPLIFIERS (Barlows and Powermates)

You can also choose a long focal length eyepiece with comfortable eye relief and use image amplifying lenses to increase power.
Tele Vue makes Barlows and Powermates (an improvement to the Barlow-type design) in magnification factors of 2x, 2.5x, 3x, 4x
and 5x.
PARACORR Type-2 (Parabola Corrector)

If you have a Newtonian or Dobsonian reflector that’s f/5.0 or faster, you should seriously consider using the Paracorr to eliminate
coma, so your full field eyepiece sharpness is not compromised. Paracorr also acts like a 1.15x image amplifier, so, for example, a
1000mm f/4.5 scope becomes an 1150mm f/5.2 scope. Adjust your eyepiece focal length choices accordingly. Paracorr Type-2 isfor scopes as fast as f/3.0.
HIGH-POWER VIEWING

Once you’ve selected an eyepiece set based on field stop sizes, calculate the magnifications produced with your scope. For
planetary or double star observing, you’ll want an eyepiece in at least the 150x range. For determining maximum power, a goodrule of thumb is to use no more than 60x per inch of aperture for scopes with apertures up to 6". Higher magnifications may still bepleasing but will not likely reveal any additional detail. Realistically, the atmosphere will usually limit your planetary observing to a
maximum magnification of about 300x, no matter how large your telescope aperture.
Basically, you’ll be choosing low and medium power eyepieces by field stop increments to "frame" the subject, and high power
eyepieces by magnification increments (based on your scope’s aperture), to reach the optimum contrast and resolution for viewing
planets and double stars.

Dobs” and “Determining When To Use Eyeglasses”.
