September 22, 2020: Result of 13h 2.5 min on M27

Managed to grab 2.5 hours and a bit on M27 through the Meade SN6, ASI186MC and Optolong L-eNhance filter last night, and added these to earlier hauls. First without unsharp masking, just stacked and stretched in APP, and a little boost in red in Gimp using curves gives the following result:

Using stacking in APP, unsharp masking in FITSwork and stretching in Gimp gives this:

The core is slightly less blown out, and more detail is coming out in  the outer regions. I think I will run it through my own unsharp masking routine later (gives more control without overshoot effects). Might also want to crop the image a bit
