I am just now trying PixInsight trial. I have been doing astrophotography for a couple of years using a one-shot color camera (ZWO ASI 071). I have been using a different image processing software but decided to give PixInsight a try. I plan on reporting back to my astronomy club on my comparison.
I was able to go through an entire project yesterday starting with building bias master, dark master, flat master. The problem I encountered is an overall purple cast when I calibrate the lights, biases, darks, and flats and then Debayer the result. I always select RGGB during debayer since that is what my ZWO ASI 071 calls for. I expect to see an overall green cast. I have been using Warren Keller book and process tutorials from on-line sources.
I tried to calibrate the biases, darks, and lights and then debayer them. I did get the expected green cast.
It is only when I also add the flats to the calibration process that I get the purple cast.
I am doing something wrong? It almost looks like when I add the flats to the calibration process the reds and blues become prominent and I lose the greens.
Shouldn't I always see a green cast after debayer?
I am just starting using PixInsight and would appreciate some guidance.
Thanks
Roger
