Firstly Nathan, if your NEQ6 is decently aligned, you don't need to waste your time autoguiding at a focal length of 180mm. Your mount will give
you round stars for at least 5mins at that focal length. I image unguided
for 120 secs at 1000mmm. f/l.
Secondly, if light pollution allows it at your location, go for longer subs, and more of them.
