Subject: C8 Coma for astrophoto.
Date: Wed, 26 Aug 92 16:38:19 GMT
Organization: Netcom - Online Communication Services  (408 241-9760 guest) 

I've started to use my C8 for prime focus astrophoto.
The result look sharp at the center of the field but i'm
surprised to see how important the coma is at the edge
of the field !
What's the point of a Schmidt if it's to get so much coma.
Also for guiding, coma stars are not that fun...
  
Are there any coma corrector that would fix that without
changing the f ratio ?
Also i would like some comments about the reducer/corrector
of Celestron. How sharp is it at the edge of the field.
How is guiding with that reducer ?

I use an Ultima 8 and the radial guider from C.

Thank you for your comments.

	Be aware that the Astroscan's mirror is parabolized by the

My in-laws in Kansas say that there will be an annular solar eclipse
there sometime next spring or the following spring and want to have
an eclipse party. It is necessary, however, to know the exact date since
the wine will need to be aged for a while and we need to breed the cattle
for preparing steaks. Can anyone on the net furnish this vital information?
Also, any info on the time of day, degree of coverage, and will we be
disapointed? I experienced the total eclipse in Norfolk a few years
ago and it was almost a religeous experience. I have not experienced
an annular so I'm not sure what to expect. Any wisdom? Thanks in advance.

Could someone tell me what a double lined spectroscopic binary star is. I know
that a spectroscopic binary is a binary star that is known to be a binary by 
looking
at the spectrum and seeing that an emission line is double (right?)

Also (this'll probably be in the reply anyway!) what is the difference between
a single lined spectroscopic binary and a double lined spectroscopic binary.

 Please E-mail responses direct to me.

Edmund Scientific (1990 catalogue)

They have such neat stuff, I hope they never go out of buisness.  Their

There are now two versions, a small one and a big one.

Professional astronomers call the solar system the "solar system".
The Milky Way is called the "Milky Way" and the Sun is known as the "Sun".
The purpose of terminology is to prevent confusion. No one is

i would imagine that crystals added to a solution supercharged with
gas would provide a great source of cavitation nuclei (minute cracks
from which bubbles would grow due to vapor pressure differences
overcoming the surface tension at the gas-liquid interface).

you can test this 'physical' theory by tossing sand, sugar, or

                          REACTOR PHYSICIST


                   Salary:  CDN $35,000 to 57,500
             depending on qualifications and experience


        A Reactor Physicist is required to perform nuclear reactor core
        design, safety assessments and related support, and to develop
        computer programs to assist analysis of data.  The work may
        include fuel characterization studies, radiation transport
        calculations, fuel geometry optimization, and reactor operation
        and safety-related assessments.  The above tasks include code
        development to expand existing capability, automate routine
        tasks or improve code efficiency.

        An advanced degree in Physics or Nuclear Engineering and a
        strong background in computer programming and utilization are
        required for this position.  A bachelor degree with high
        academic standing and relevant experience would also be
        considered.

        While previous experience with neutron diffusion theory,
        multigroup neutron transport theory or Monte Carlo calculational
        techniques would be a definite asset, less experienced
        candidates with an ability to adapt quickly to new challenges
        are encouraged to apply.  Demonstrated technical report writing
        and oral communications skills would be useful assets.

        The Whiteshell Laboratories is located at Pinawa, an attractive
  recreational/residential community on the banks of the Winnipeg River,
  northeast of Winnipeg.  We are a 1000 employee laboratory with
  research interests in both nuclear and non-nuclear activities.  The
  laboratory has a strong, comprehensive complement of in-house support
  services/facilities and research is well supported with advanced

************

Microwaves are a type of radiation that has nothing to do with the
radiation commonly associated with "DANGER - CANCER".  The latter
is nuclear radiation and consists of high-energy particles such
as alpha-rays, beta-rays (electrons), and gamma rays.  The way
such radiation causes cancer is by destroying, more or less at
random, the highly evolved biological molecules.  Sometimes the
the part of a molecule that's destroyed is the gene that controls
cell division.  When cell division is uncontrolled you have cancer.

Microwave radiation does not interact with matter in this way, at
least not at low power levels.  (Nuclear radiation at low intensities
can cause cancer, however.  But intensity and power-levels are not the
same thing in this context.)   As you should have figured out by
now, microwaves HEAT matter by inducing the random motion in molecules
and atoms that is associated with heat.  If microwaves destroyed the
biological tissue in the manner that the "radar gun lawsuits" allege,
then people would be very reluctant to eat food heated in microwave
