2. How do I Find stars and nebulas I want.
3. How do I take pictures with the scope and a camera??
4. When is the best time for observing?
Yes... I am a total noob...
Thanks,

1. In periods of good seeing the 10mm will be useful for planets like Jupiter, but if the stars are twinkling heavily use the 25mm. For nebulas I find the 10mm useful fo seeking out small scale structure within the nebulas. I suggest the Trantatula Nebula in dark skies is a must with the 10mm
.
2. The 50mm Finderscope in dark skies should be all you need to locate stunning deep skie objects like large nebula and star cluster. For fainter objects you can either use a finders chart or a Go-To software which you can use with your Dob like the
Argo Navis which Im currently saving up for.
3.Taking pictures with a Dob isnt nessacarily hard. As the Dob isnt originally a Go-To you cant take exposures of deep sky objects. Howver, you can still take great images of the Moon and Jupiter which I have done.
Heres my best images of the Moon and Jupiter taken with a 4 megapixel camera-
4. The best time to obsreve is probably 2 hours after sunset as the sky would have cooled a bit. I would also suggest leaving your telescope outside 1 hour before you observe so the telescope can cool to the outside temprature.
