excellent, especially in the conditions.  For dritique, Id say dial back on the noise supression a bit.  Other than that-its noce to see an M51 with decent dynamic range for a change.

Hi,

Given the conditions, the image is nice but some light pollution still remains, especially on the right hand side of the image. It is easier to visualize it if you look at a smaller version of your image.

I have managed to correct the issue on the jpeg file (something which is sub-optimal of course) by using ABE in subtraction and normalize mode, with a model of order 2. I am sure that you can do better as you have the raw data at your disposal smile

Nice image with good color but target is very small for that FOV.

Good image, nice colors. Sharpness could be a little enhanced with - for example - Topaz Labs Denoise AI. It gives spectacular results.

Is Topaz worth it for astro images? not sure if the AI can handle that kind of image

Definitely, according to my long experience !
