Hey fellow astronomers! I just bought myself a secondhand Newt Optex OP600 reflective. It's a 8" with 1000mm focal length. Pay $330 for it comes with 4 eye pieces.
Some dumb questions i want to ask are:
1)What are each of the eye pieces for?
a: Plossl 9mm
b: Plossl 4mm
c: Plossl 25mm
d: 2x Achro Barlow
2) What accessories do you normally get when you purchase a brand new telescope?
3) I want to see deep space objects, will this do?
4) There is a small dent on the barrel, will it affect image quality?
5) What do you use to clean the lenses/mirrors with?
6) If anyone has a manual to this, can i get a copy?
Many thanks and much appreciated.
