Thats a crop of am wide field image of the Lagoon and Trifid Nebulae. I finally got myself a PixInsight License and tested a bit how much better (or not) the calibration and stacking is compared to AstroPixelProcessor. Well, they are both super close in the results but PixInsigt produced a much better drizzle result. Other things (like the RGB combine) worked for me much better in APP... so, I thought its a decent result despite it is a crop from a 250 mm RedCat 51 wide field image and worth to present ;-)
