Description

My first run at this well-known target. I found it needed a lot more integration than I expected -- or maybe I'm just getting pickier!

Two distinct sets of sessions -- first was using my new (second time only) remote setup at home while on business travel -- this is the life! Then I realized my GM8 was tracking quite nicely after redoing the PA, 1" RMS, so I moved off my old 60-second exposure habit and went for a second batch at 120sec.

Final integration is my longest ever at nearly 24hrs!

I had hoped to use this target to get better with Generalized Hyperbolic Stretch, but it was a bust -- I never had time. Thar tool is just not obvious, requiring a lot of iterative tweaking.

Capture: ~6hrs of 60sec exposures each filter, plus ~2hrs each of 120sec. Total integration ~24hrs. 

Processing: PI WBPP, Dynamic Crop to trim edge artifacts, Color Combination (SH0), NoiseXterminator, HT to STF, SCNR remove green and magenta, StarXterminator to separate nebula from stars, CurvesTransformation for contrast and saturation, EZ Star Reduction, Dark Structure Enhancement, Lightroom for final aesthetics.
