Lagoon Nebula

Here's the next thing I've spent processing from last weekend at LMDSS.
It's M8 aka the Lagoon Nebula.

33 x 300 second subs. Only subtracted darks. My usual setup with a 200mm f5 Skywatcher newt, Canon 700D (unmodified), QHY5LII guidecam running through PHD2. I got up about 3am to set this one up and it ran until the sun came up.

Processing is entirely PixInsight. Main processes have been a deconvolution, TGVdenoise, and some messing with curves and the histogram. For one of the two images I ran HDRMultiscaleTransform, which had interesting results, but I'm not sure which version I like best. I was messing with HDRMT before stretching the data and gave up because I couldn't get rid of artifacts, but accidentally ran it after stretching and it worked great.

Proper versions here:

non-HDR: http://astrob.in/full/181916/0/
