Hi Andy, you will be able to see the moon in close up and saturn, jupiter etc. you will also see nebula's and other deep sky objects. The only drawback I can see with this scope is it may be a catadioptic which can be hell to colomate, if you can go an extra £15 Stockport Binocular do the same telescope with a shorter focul length with drive motors for £165 (a better scope). I would sugest holding off buying your first scope until you have been to Pex Hill and had a talk to a few people about the pros and cons of different types of scope (you will be able to try a few types up there, weather permitting). There is nothing worse than spending good money on a scope only to be dissapointed with the views.
see you soon

Thanks, again Brendan, for the quick reply. I did actually find that one on Stockport, its the scope above the one you were listing on the same page...
Pay Day - Monday
Pex Hill - Wednesday (if she's up to it)
Buy Day - Saturday
It all works in sequence :-) Just trying to get an idea of what's what before i take the plunge...
I notice the difference in Focal Lengths between those two scopes, and i'm wondering... is it that a lower F number gives a better view?!?
Also, a scope which is motorised, does it HAVE to use the motors? Or can you move it manually?!?
Thanks again, and sorry for being a pain!

Hi Andy, the shorter focal length is better for deep sky but will sufice for moon and planetary, the longer focal length, if catadioptic will have a lense in the focuser ( so as to increase focal length) this can have its own problems. The motorised scope can still be used manually, one of the benefits is you can easily stay on what your viewing as once aligned it should keep the target in the eyepiece (ideal for imaging).
see you soon
