Six nights in March.

P.S. I'll keep trying to pull out the hydrogen. I'm learning to "clean" the data further.

Too much sharpness applied and stretched with a lot of light channel.

Thank you for your opinion! Regarding sharpness—in my view, that’s a matter of taste, and there’s no arguing about taste. About the light—is there somewhere I can read more? I don’t understand what you’re referring to.

Colors are limited due to the Luminance channel—it's heavily stretched, likely processed in Siril.

Very impressive! Especially given the level of light pollution! :-)

A mesmerizing photo. For me, as a beginner in this genre, it's a real benchmark.

Thank you for your comment. Patience and hard work. My first works were far worse than this; the key is persistence and patience. Clear skies and success to you.
