Veil nebula ✨

I took this image a few months ago, in October, while I took data for my school project. So it was something like a side product. This image was quite difficult to process as the CLS filter makes the stars reddish and too popped up. These days, I know how to reduce this negative impact during capturing the data, but I didn't before. So I think the result would be better if I took it today. But what can I do. At least I have this, and hopefully, I'll retake this object better in the future.

The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation of Cygnus. It's a supernova remnant, which source supernova was a star 20 times more massive than the Sun, which exploded between 10,000 and 20,000 years ago.
