This is a first attempt at an HDR composition in PI. I went through all the old data and grouped all of my M42 subs into exposure length and ISO, then preprocessed each before doing and HDR integration.
All of the data is from my Canon 60D during the earlier part of the year before modification and sensor temperatures were anywhere from 26 to 30+.
After tossing any subs that had any issues I ended up with
10 x 60s
88 x 30s
58 x 20s
30 x 10s
Matching darks were still sitting with the 60 and 30s subs, none for 20 and 10 since they were more for testing when I took them. Flats for all stacks.
I see why photographers spend the money on high end monitors now, the difference between a Mac / retina screen and my linux machine with a regular monitor is night and day when trying to work with high dynamic range. I could clearly see the trap much earlier on in the processing on my mac. I had to really push it to see it at all on the regular monitor.
I think this process would benefit from the addition of much longer exposures to capture more of the faint nebulosity.
