Description

Original: Dodged clouds to get this data. Very basic processing in PixInsight using WBPP script.

Revision C is some histogram adjustments. I noticed that the jpg/png versions did not have the same histogram as the xisf I was editing in PI.

Revision D includes 4 days of data. 95 subs. Better processing with LocalNormalisation and DrizzleIntegration, etc. Cropped to remove integration boundaries from the various nights.

Revision E is more processing applied.

Revision F is with 3 more nights of data, although the final version removes about 10% via SubframeSelector (restricted by FWHM and Eccentricity). The framing is due to the integration boundaries, so this may turn into a mosaic in the future. Have tried to use HDRMultiscaleTranform, LocalHistogramEqualization and the script DarkStructureEnhance. Since this is the first time I've tried to use this flow, I will not be surprised if I do a reprocess at some point.
