Hi,
Here's some stuff ...
My (one of the earliest) Celestron NexStar does not have any
manual-override. I found that to be a serious shortcoming. When I
don't feel like hooking up the battery or listening to the motor, I
can't use this one. If you buy any "goto" scope, I recommend holding
out for manual operation ability..
I have trouble thinking of any 8" scope as "compact". Even my
NexStar, which is a 5", hardly qualifies as "compact". I have a Meade
ETX 90 RA (approx. 3.5" - mine's not a "goto" but Meade does have a
"goto" in that size) is my "compact" scope.
You decrease size/weight, but also decrease light-gathering when you
get a smaller scope. It's a trade-off
If your scope will be doing a lot of traveling, you'll be needing to
collimate (adjust the alignment) more often than usual. So whatever
you buy, make sure collimation isn't a PITA.
Do lots of research before you buy. Better yet, find a local
astronomy club and go to one of their "open" nights ... you can see
lots of different scopes in real-life use (and get lots of different
opinions about your own situation).
