M20
Here is M20, faults and all. The de-blooming algorithms in CCD stack are not so good (IMHO). So there is a bucket load of de-blooming artifacts in this image. It comprises
10 hours LHaRGB as follows:
Blue 24 * 5 mins unbinned @ -20c
Luminance 24 * 5 mins unbinned @ -20c
Ha 24 * 5 mins unbinned @ -20c
Green 36 * 5 mins unbinned @ -20c
Red 12 * 5 mins unbinned @ -20c
All other details as per the M16 image (no deconvolve). De-blooming represents my biggest challenge. Anything more than 5 mins exposure creates significant blooms and they can be challenging to remove
I've done NO processing other than calibration and stacking. Am running out of time
