Default QUESTION HELP needed on a Celestron Cassegrain

Ok, I am shopping for a new telescope, one possibility is the 10''
Orion dobsonian reflector, my budget is 1,000.

But now I see at astronomics.com a scope normally costing 2400 on sale
for 1200, i would stretch the budget if you guys think this particular
scope is a big improvement on the Orion 10'' dob, i am particulary
interested in deep sky


Celestron - C8S-GT Advanced Series 8" f/10 computerized go-to
Schmidt-Cassegrain

That is the scope, this is the web address

Thanks again for your help

Default QUESTION HELP needed on a Celestron Cassegrain

The 10" will show you more, the 8" will be more compact, and has tracking. If
you are looking for optical performance, the 10" is the way to go. The 8" will
make a nice observing package though. In that price range I would be tempted
to pick up an LX90, or a used lx200.

The C8s-GT is a 8" SCT on a CG5 mount with GOTO. If you want portability,
GOTO, tracking, reasonable aperture on a dressed up CG5 mount, I would
advise you go with the C8S. This scope has _many_ features you will never
find on a Dob, but some guys like a very simple telescope completely devoid
of any electronics (I'm not one of them). So if $1,200 is your absolute
limit, go for it...otherwise, add a few hundred and buy a Meade LX90.

Wonderful deal, but if you are a visual observer (that is, you are not an
astrophotographer) then the best deep sky performance will come from the
larger (and faster) aperture dob. You said you were particularly interested
in deep sky, and that's what I'm recommending.
I own a C-8 and have owned a 10" newt of similar performance to the Orion.
No question, the newt (dob) blows the C-8 out of the parking lot visually.
If you were particularly interested in planetary observing or deep sky
astrophotography, I'd have recommended the C-8. Visually, it's weak on deep
sky compared to the 10".

Regards,
Etok

Thanks Etok, but will I lose a lot with the planets if i go with the
Dob, because I do want the better deep sky, but i am also into the
planets and don't want to lose too much

Also the Dob is 650 while the other is 1299

A 10 inch DOB will do a nice job on the planets. Optically it is likely to be
a better performer, given the added aperture and smaller central obstruction.
Deep sky the added aperture is definitely a plus.

But the issue here is tracking. The lack of tracking on the DOB means that you
will have to track the planet yourself, I find this is not a problem, but that
is my choice.

Each person has different priorities, different goals. If you are like me,
like simplicity, quick setup, lack of added gadgets required, the DOB will be
the right solution.

My suggestion is to try to find the opportunity to look at these scope in
person, try them out, see what appeals to you and what doesn't. Check out the
issues with setting up the scope, see what hand tracking is like, star hopping
vs goto, seated vs standing viewing.....

Those catalogs paint some pretty pictures and have some flowery sounding prose
that can make an old hat this game get excited about some telescope or eyepiece
only to realize, "Hey I had one of those and I really did not like it."

So, try to get a feel for what you will be getting before you get it, see what
reality is vs the dream.

When those boxes show up on your door step, that is not the time to find out
how big a 10 inch DOB is or what happens to your neck when viewing at certain
angles.....

I also suggest considering the 8 inch F6 dob. The optical tubes on these weigh
about 22 lbs rather than the 35 lbs of the 10 inch, fit in a car better and
still provide stunning views of the deep sky.

If this is your first scope, this is a good place to start IMHO.
