Another Colorful Swing-by for Comet C/2022 U2 (ATLAS) and IC410, 2023-02-12 After passing the Flame nebula the night before (seehttps://astrob.in/04rb75/B/), 12th magnitude comet U2 ATLAS has just passed the emission cloud IC410 - the tadpoles. The comet is surprisingly large in envelope and it has "that" greenish color to it. This is a rather deep image with well over two and a half hours of integration time. I feel like I can see a faint dust tail extending at what position angle?
