Looks good to me. Only Astro guys will know if you need more subs. But we none astro guys still admire the work and stay involved even when we have little to contribute
I do a lot of AP and get fairly poor results (much worse than this!), so I've worked on getting the best possible result on the stacked image. I think you could pull out more detail, and darken the background more here.
But as I said, you've gotten a much better image of M81/82 than I ever did.
Hey Les, this it looking great!!! I like the detail you got, and the Ha data sure adds a lot. In my recent m81/82 I wish I had gotten some Ha data, and I will probably try to do that this month.
There is an issue with Uploading Photos (attachjments). I am not sure what the problem is, and I am looking into it. You can still try to Create your Threads and Upload your Photos, but it is hanging up during the Upload.
