Description

Revised M20 using the same data but much "lighter" processing in PI, resulting in smaller stars and better visibility of faint nebular structures and dust lanes. Sometimes a full blown LRGB workflow in PI does not yield the best result (at least not with my still very limited skills regarding PI). I have also used a new Masterflat since the old one was messing too much with the colors.

Description: Better processing in PI (calibration, FWHM-weighted Integration, stretching) resulting in more realistic colors and much reduced image noise.

F

Description: Reprocessed, using RC-Astro's NoiseXTerminator and BlurXTerminator.

G

Description: New processing, using GESD instead of RCR integration. GESD appears to be significantly better than RCR for my data. Also used the new BlurXTerminator V4 algorithm.
