Description

I had a lot of software issues shooting this cluster. But I wanted to shoot a large galaxy cluster with a wider view using the new ZWO ASI2600MC-Pro. Unfortunately I lost more than two days of images due to poor focus. I only ended up with 169 total 2min subs. I might revisit this one day to improve it, as from my light polluted skies, it's lacking some real depth.

B

Description: Added two more hours of data and reprocessed. A little bit more color now.

Description: I added about 5 more hours to this, and it's starting to look better. This APSC sensor is showing much more CA on the outer edges of the frames. So either the reducer isn't well corrected, or my distance to the sensor isn't exact.
