Hi,
This is my first thread thingy (having just created an account yesterday) so I'm not entierly sure if I will clicked the right buttons or not and what will be the final result.
Anyways, I currently have 2 relatively small reflectors (114mm and 130mm and 1 quite old refractor (60 mm) and I was thinking about getting either an 8" or a 10" (If my wallet will be big enough) new Dobsonian, probably Sky Watcher brand). I was curious if anyone knows a bit about them if you could help me out a bit.
If anyone knows the answers to any of these it would be much appreciated.
.What magnitude would be visible through either the 8" or 10"?
.What sort of quality would be given for astrophotography?
.How long would a planet such as Jupiter stay in the field of view in the eye piece?
.If a CCD webcam was attached would it pick up any decent quality?
.Would it be worth getting a Dobsonian that doesn't have a motor drive in it to so it is used manually?
.What sort of difficulty is there in locating Nebulae, Galaxies, stars etc. with a Dobsonian of 8 or 10"?

It is much appreciated, thanks in advance.
