The ASIair makes adding images to previous results pretty easy, and last night was a test of that process. Can you see a difference?

This image uses 85 subs over the course of 2 sessions 2 weeks apart. After Deep Sky Stacker did its evaluation thing, another 22 minutes integration were added to the original image (42.5 minutes total).

I feel like I am seeing more detail, deeper colour with the added 22 minutes. The horses chin is more discernible, for instance.

Yes. I reworked the 42 minute image and will create a post with it. Thanks!
