Finally got a clean stack of comet 13P/Olbers — 3 nights of data

Three nights of fighting moonlight and a temperamental guiding setup. Last night everything clicked—the sky stayed clear, the mount behaved, and the stack came out with a faint but unmistakable ion tail. It's nothing Hubble would look at twice, but it's mine, and it reminds me why I put up with all the cold nights.
