The decision to purchase
I was home alone, on call, one weekend. Feeling lonely and depressed, I decided to
extend my photography hobby by purchasing a telescope. I looked up our local
telescope dealer and rushed over to pick one up. I knew nothing. My first
question to the fairly knowledgeable sales person was: "What kind of magnification
does this thing have?" as I pointed to the fork mounted Celestar 8 sitting in the
show room. The sales guy politely told me that I should probably do some research before I
made a decision to purchase a scope. He recommended Star Ware. I purchased the book and
went home and read it that night. After still being convinced that I wanted to do
photography (and Star Ware helped my convictions in that regard), I went in the next
morning and purchased the C8 in the show room. I was ecstatic. I had always wanted
to get involved in astronomy. Visions of brightly colored objects flashed before me in my
mind as I drove home. I didn't have a clue.
Impressions
The scope came with a 26mm Celestron Plossl, a worthless 6x30 finder scope, a fork
mount wedge with clock drive, and Digital Setting Circles (DSC). The scope is a
Schmidt Cassegrain Telescope (SCT) which means that the optics are composed of three
mirrors to reflect and fold the light beam before it gets to the eyepiece. This makes the
total overall length of the scope very short.
The wedgepod is a combination wedge and tripod. As with many low cost things that
serve the purpose of two or more other things, the wedgepod has some serious
problems. You can not adjust the height of the legs. You can't tighten down anything
very well. The angle of the wedge (which determines your polar alignment) had serious user
interface problems. A set of small allen head screws held the entire weight of the
scope... trying to set the scope at a specific angle is very difficult since you
essentially have to hold it with one hand while you tighten the screws with the other and
hope they don't slip on you.
Since the scope is on a fork mount and the tripod isn't far off the ground, most
observing is performed while seated... or in some twisted position on the ground with your
neck strained as you try and squeeze your head up under it.
My scope out of the box had some serious collimation problems. Since I didn't know
anything about it, I looked at winged stars for the first three months. Nothing in
the documentation lead me to believe that anything could be done about the images. The
documentation on the scope and its use was dismal. The star chart which lists stars in the
DSC is cut short... not printed in its entirety. Instructions were incomplete and down
right confusing.
First Light experiences
I got the scope home and set it up in the living room and squeeled with delight.
It was sooo beautiful. That night I took it out for a spin in my back yard.
After a couple of hours of frustration, I finally found the ring nebula M57. I was
not impressed. It was this dim thing that I couldn't focus! I coulnd't find anything
else. I convinced myself that what I needed was a darker sky so I hauled my treasure
chest of optics to my place in the Sierra the next weekend. I spent the first night trying
to get the DSC to work. It didn't. The next day I set up the outfit on the
deck in front of the cabin and moved the scope back and forth, up and down, trying to see
which motions did what on the DSC. It wasn't long until I figured out that the settings
shipped with the DSC were incorrect for the scope. 5 minutes working through the settings
made sure that they were correct. It was then that I learned my first lesson:
If it's broke, don't fix it at night. Spend the precious darkness observing or
tuning your knowledge of the sky.
That night, I was treated to things that I had never seen before. But... I still was
expecting much more than I could see. There was no color in anything and I was terribly
disappointed in that. Globular star clusters were boring to me (this has changed
significantly!) because they were just some stars clumped together. I wanted to see
galaxies and nebulae. Eventually I did hone in on the objects of interest and my
fascination with the sky grew.
Since then....
I continued to set up the scope where I could and when I could. I never did find out
about star parties or visit with anyone else who was into the hobby. BAD MISTAKE!
But after a couple of months, I saw a notice on the SAA newsgroup about an in town event
sponsored by the SJAA. It was here that I finally met other observers with various types
of scopes. It was there that I found out about Fremont Peak and I started to visit
that site on a very regular basis.
As time went on, I found much to my dismay that the cheap reflectors made out of
cardboard were able to "see" things much better than my SCT. And to make
matters worse, I found out that much larger aperature newtonian truss tube instruments
cost much less than what I paid.
I tried photography. I spent many dollars on all the doo dads that you
need. The scope and mount combination were not adequate to the task. I gave up in
frustration.
SO... I discovered that my SCT had poor contrast (as most SCT's do), wasn't as good as
a cardboard telescope for observing, and had little hope of ever capturing a decent photo.
As my interests turned to observing, I abandoned my interest in the SCT and ordered an
18" Obsession.
I didn't lost my desire to photograph however and I kept the C8. Late last fall,
I purchased a Losmandy G11 mount which gave the C8 some new life. I did some
experimental photos with it and had favorable results. The C8 on the equatorial
mount seemed much easier to use. I collimated the tube carefully and found a new
friendship with the instrument.. it ain't that bad.
I mounted the instrument on a GP mount and since then, the ole C8 has seen much more
use. It is now the scope that I take to star parties. I can stand and observe. There
is no more twisting in convoluted positions to get to the eyepiece. And the tracking
of the GP seems to be just a bit nicer for some reason.
Conclusions
Automobiles come in various types and sizes and serve well for specialized purposes.
Some try to satisfy all requirements. Yes, the SCT's are the minivans of
telescopes. They are general purpose instruments not really great at anything. But
you can try. There is no end to the number of cool techie accessories you can buy to do
this or that. But in the end, you still have a minivan.
