Description

Finally acquired some images of the Crescent Nebula I was happy with, resolving some of the wispy edges blue nebulosity.  Tracking was still a bit of an issue (working on that) but ok.  Seeing was good too, 3-4 Clearsky scale.  The final image is an average of 6 live-stacked images of 40,40,41,40 and 46 x 3 sec frames plus 1 70 x 1sec frames.  Prior to averaging, background was subtracted off with Pixinsight DBE, then aligned and integrated with DrizzelIntegration.  Color corrected with Background/ColorCalibration.  I used RangeSelection to mask and protect the wispy blue edge prior to lowering sky background a bit.  Finally image was run through Topaz Denoise AI using Clear, med noise removal and low sharpness enhancement.
