If you like cool toys, you need to get a green laser. If any green laser is not good enough, you need a Wicked Green laser. They speak for themselves.

Never underestimate the power of a 2" dielectric diagonal. Williams Optics makes a good one that is, a little, more affordable than the others.

Have you ever wondered why you buy great optics for your observing and then look through them with plastic lens glasses? I have. I bought a pair of "glass" glasses with anti-reflective coatings and use them just for astronomical observing.

For photographic purposes, a focusing aid can be quite handy. You will never get as accurate without some sort of aid, even when viewing it on a screen.
