That's excellent work, Jerome!

Depth is truly magnificent, with the wide-field revealing stuff that we were unaware of. Contrast is great.

Sharpness seems limited only by pixel size. We know nothing about drizzling, which is black magic, but it might turn out to be relevant for your scope and camera combo.

Tiny tweaks might be to set the black point more carefully - it's not clipped but there is a magenta cast in the blacks. Fixing that reveals a very slight excess of green, so you could then reduce the green most microscopically so that all three channels balance.

Oh for a mosaic with the Whirling Dervish included in the image!

Best,
Mike and Trish
