Description

I don't think I did a great job of utilizing color here. I feel like there should be more than just blue to it, and that's even after removing a pretty significant blue hue from the automatic background extraction...may revisit the postprocessing at some point down the road when I actually know what I'm doing.

I considered adding in some Ha exposures, but really haven't been happy with the huge amp glow I get with Ha exposures on my ZWO ASI 183MM. I'm currently waiting for my 1600MM to arrive, which hopefully will make that amp glow less of an issue.
