M33 - Triangulum Galaxy

 

 

Here's a quick processed image of a session from back in November 2023. The integration time on this image of M33 is on the long side for me, with just under eight hours of integration time between R-G-B-Ha channels. With that in mind, you can pick out the glowing red regions of star formation. Nevertheless, I wasn't really happy with the overall noise level/background/calibration, and there's some pretty severe fixed pattern noise.

For that last issue, I need to look into my dithering setup. For the former, some of the problems have been fixed by my new field flattener (the William Optics one that came with my scope has always suffered from bad and uneven vignetting, and bloated stars at the corners, which seems to be fixed by the new Orion flattener). 

Also, I know it's time I finally figured out how to do a good job with foreground star reduction... but not today. 

Either way, I thought I'd share - Triangulum!
