Description

This target is more dim than I had expected. That made framing a bit tricky - even with 60 second framing shots, the core was barely visible. Total integration time was only 64 minutes due to some unknown issue with guiding/tracking. I had about 10 of my subs showing two stars for every one - similar to what happens on windy nights, except there was no wind. (Had to discard those.) Still trying to figure out what the issue was...

This is a crop of the full image. I needed to remove some vignetting and dust donuts.

Anyway, I had fun with this target. Thanks for looking!
