This is a fresh attempt at the California Nebula which was one of my first projects a year ago when I really became serious about the hobby. Last time I used a ASI6200MC color camera and my FSQ85. This year I used my ASI6200MM mono camera and my FSQ106 and I tripled the integration time from 8 hours to 24 hours.
I am currently using my RST135 travel mount as my second home mount while my Avalon M Due is being repaired. As a result, my guiding could be better which robbed me of a bit of detail.
I have been playing around with pixel math and color mapping to try to bring out some differences in the Ha and S2 data. They are both very strong signals in this target so most California nebula shots tend to be heavily biased to one color. My goal here was to differentiate between the two data sets with slight variations in the Oranges to bring out the structural differences. There is still more to do here, I will try again as my skills progress.
