A quick and dirty processing of a data set from Calstar 2017.
It's been a long time since I finished an astrophoto. I've not been happy with the data that I'd gathered at various locations including the backyard for several outings. Finally, I decided to strip down to the basics and rebuild my process. For this dataset, I tweaked guiding parameters to give longer correction pulses. This improved the speed at which the setup recovers and thus there are more valid frames. I also recentered the drawtube on the scope with using CCDInspector, improving off-axis star images. I also rebuilt the automated focuser, improving gear mesh, giving more predictable and tighter focus.
Overall, this gave me a quick set of decent data to work with in Pix Insight. I'd like to have more color in this image, and I may revist the steps to improve star color.
8 Red
6 Blue
8 Green
6 Lum
All subs 10 minutes
All data gathered from September 21 to 23, 2017.
Quick processing in PixInsight:
Preprocessing Script
DBE on merged RBG
Masked stretch to .125 average background, 250 iterations for RGB and Luminance.
L added to RGB.
Curves used to boost saturation.
Annotation script done on brighter objects.
