Seem like taking forever to collect the data based on the sky condition near North California. I got about 4 reasonable whole nights at the early and end of August.
I used the Weighted Batch Preprocessing script and Normalized Scale Gradient (NSG) script to integrate images for each filter. I am impressed by the Pixel Rejection Algorithm: Generalized Extreme Studentized Deviate (ESD) when I had more than 30+ subframes. Both NSG and ESD really improve the image quality, highly recommend it.
Any C & C are welcome. Hope you like it. Stay Safe (away from Fire, Smoke, Flood, Covid).
