Thanks for the advice. All very valuable.
I must say that I am starting to feel a little guilty spending my piggy bank coins when so many posters here seem to getting good image results and experiences with must lower cost set ups.
My impression so far is that the mount is the most important equipment item in any set up and should make up the bulk of the initial outlay. Unfortunately the reflector and refractor which I currently use are very old with very poor optics and I don't want talk about the 2 Barlow lens.
i am keep to see deep sky objects better and want to get into astro measurements. Measuring the orbit speed of planets, and their moons etc. long term observations that reveal intricate motions and behaviors. The imaging is almost secondary to that goal.
The skywatcher NEQ6 mount is looking attractive, not sure if I can afford the AZ EQ version.
Can anybody assist with why an AZ option is handy and whether it does anything better than the standard GEM? Is it just simplicity of set up and operation?
Cheers
