Hi Quack!
Good selection of first scopes. The 8" is better than the 6, and the 10" is better than the 8". The 12" is great too, but then you lose some portability.
Accessories you need include:
- Collimation tool (cheshire sight tube)
- Red light
- Planisphere
- Eyepieces
That'll do to get you started!
to IIS! Keep asking questions!
