| Description | Captured right around astronomical dusk, at roughly 20° altitude, with a thin cloud layer playing havoc with transparency. This part of the sky happened to be reasonably clear at the start, then clouded up, cutting short my desire to continue gathering data. Another William Herschel discovery, this one from 1781. Color on this object is very much dependent on where you set the color sliders. I was looking for a neutral background, so these colors popped out. |
