Description

I recently enjoyed another night of good seeing, and was able to collect 30 5-min subframes of Carina using a 3nm H-alpha filter. Later that night clouds rolled in and I had to suspend the session. There is a batch of bad weather coming, so I decided to use this new H-alpha data, in combination with OIII and SII data from 2021, to see its effects on general resolution. The stack of H-alpha frames resulted in a FWHM a bit over 1.4", which I used in the G and L channels of the SHO composition.

The sharper H-alpha dataset, combined with a different and more up-to-date processing, resulted in an image full of interesting details in all corners. In what follows, I have included juts a few that caught my eye.
