Description

NGC 1491 (also designated SH2-206 and LBN 704) is a bright emission nebula and HII region, located on the edge of a vast cloud region of neutral gas, about 10 700 light-years. HII regions are well known for being places where new stars are born and are created when ultraviolet radiation from hot stars ionizes the surrounding gas, causing it to glow in visible light. The surrounding dust is also heated by this radiation, so we also see it glow in infrared light. The entire nebula is quite irregular.

I honestly saw only a few pictures of this target on AstroBin, especially in Hubble palette. I thought it was a good idea to capture the nebula and its outer Ha halo (which is not often shown). Later, I was surprised to see how much Oiii there was in the core. After countless hours of processing, I managed to bring out the core and its beautiful blue tone. However, I had a hard time keeping the noise under control. Plus, the nebula might look a little bit fuzzy and noisy.

Overall, I’m happy with the result. Criticism and advice are welcome!
