Which way does your balcony face? North-East is the best view to be able to view the planets.
The moon and planets can/will look FANTASTIC in an 8" or 10" dob, but the quality of the view will be dependant on:
1) The seeing (atmospheric turbulance). Some nights it's better than others. Some nights it's downright horrible and you can hardly bring it to focus.
2) Collimation (especially with a reflector). You need to learn how to do this!
3) Cool-down time. Leave your dob out for an hour or so before you plan to use it, this will help the views.
