Re: Some Astro Success

Congratulations on getting the comet!

You say you didn't see much improvement with stacking, but how many images are you using?

Slightly out-of-focus stars often show colours better than in-focus stars. I've seen stacks of images going from in-focus to out-of-focus, without correction for sidereal motion, and each star forms a wedge. These show the colours of different brightness stars quite nicely. Perhaps something to try once you get better weather?
