I have a 9.25 evolution mounted on a celestron advanced vx eq mount.

i have the 6;3 field reducer and a asi071 camera'

is this a good setup?

is the mount heavy enough?

was thinking maybe i should get a lighter scope like a   William Optics ZenithStar 81 f/6.9 Doublet

Fine setup for visual and planetary/lunar imaging.  Maybe could work for EAA, you'd need to ask on that forum.

 

It's a truly awful setup for learning DSO astrophotography.  About as bad as it gets.

 

Both classic beginner mistakes.  An inadequate mount, and too big a scope.  In spades.

 

The 81 is so much a better choice, it's ridiculous.

 

Don't believe me?  It's not really my opinion, it's the distilled knowledge of watching and advising beginners on here for years, seeing what works, and what doesn't.  15 minutes spent watching this video (you really only need to see the first 5 or so), could save you a whole lot of time and money.

The 071 is fine.  The AVX could work with the 81, but it depends on how lucky you got when they pulled yours off the shelf.  Be prepared to replace it with a better mount, which is the most important part of a DSO imaging setup.  You'll know if you have a problem.  Don't fight, switch.

 

This will be the best $40 you ever spend in DSO AP.

You'll need software for various things.  Calibrating/stacking/processing is the most important, it's at least half the game.  So, $200 to do that better, learn more easily, and better deal with light pollution, is absolutely trivial.  Astro Pixel Processor.  The "free" alternatives are not free in terms of your time, and your image quality.
