I've been using Pixinsight for the last 2 years and have been happy with the results. I generally have followed some tutorials online and run through the following steps with pre-processing
1) Creating Master Darks
2) Creating Master Dark Flats
3) Flat Calibration with Dark Flats
4) Creating Master Flats
5) Lights Calibration with Master Darks and Master Flats
6) Subframe selector
9) Master Lights
I do these individually per filter and it gets pretty time consuming and I'm looking for options to help automate some of these steps and help repeat them for each filter.
Is this even possible and is there any good software or combination of software that could help save time?
