Description

Everything went wrong with this one. I've been trying to capture data on this since June 11, but I ended up trashing over 120 subs due to a slew of errors. Terrible guiding, collimation problems, weather-related issues... it felt like whenever I pointed my scope at this object, the clouds rolled in.

Ultimately, I only ended up with a little over an hour per channel and it came out noisy and very posterized. I'll try again next year. I suggest not viewing this one in full resolution.
