Description

I spent way more time processing and reprocessing this than I care to admit, and am ready to put it away for a while. Did learn a bunch of new techniques and tools, and I have another two hours of LRGB data from last night that I could use when reprocessing. Certainly am starting to understand the challenge of getting good SNR under light-polluted skies, which I think is a lot of the challenge with this one. I do like the Sunflower though and am happy with the bits of detail that eventually came out.
