Description

I've been working a lot on my processing skills and wanted to try my hand at this subject again. I wasn't happy with how blown out Alnitak was, as well as the clearly visible reflection of my secondary, so I started from scratch and gathered new data. I still had problems with collimation (maybe focuser flex? - it looked good with the laser and cheshire both before and after attaching my camera) and with my secondary being visible (in my green subs, you can even see the focuser tube!). There is also a reflection of Alnitak present at the very top of the flame, but I was able to process out most of the aberrations and I think it looks way better than my previous attempts. Progress!
