While waiting for full darkness, I got started on another Moon image. It is fun learning to use SharpCap. One of these days I need to try putting the camera behind a Barlow lens, but right now I don’t want to mess with the deep sky target configuration. For fun I tried drizzling and that REALLY slowed down the processing. It’s sharper than my previous Moon attempt, but that might just be difference in phase or perhaps from being more selective about frame quality (and of course seeing always plays a huge role). I’ll have to do some experimenting with these data to see if it was worth the extra effort. I was way more conservative with the “mineral” saturation enhancement than before, and even though the colors don’t show up as much I think I like this better.

Description: In this version I used Photoshop "auto color" to balance the color channels without any additional saturation enhancement.
