This was my first narrowband image. I processed it using an HOO Palette. I’m quite proud of the results I was able to achieve with this. I had originally planned on getting some RGB data for star colors, but time and the weather worked against me.
NGC 6888 also known as The Crescent Nebula. However, I like to call it the Horseshoe Crab Nebula. This is 50 exposures over two nights. This is an incredibly faint object and I underestimated how much time I would need.
I need to work on processing. If you zoom in, you can see how my star mask affects the final image.
I also used an Optolong L-Pro filter during this image to cut down on light pollution.
