Description

Another quick and dirty Virgo galaxy for my Messier collection. I had ongoing autofocus issue with the Moonlite focuser, which meant I captured even less data than I planned. However, I'm going to have to pull the Moonlite off the rig to try and diagnose the problem and probably won't get the camera orientation the same again without a lot of fiddling, so this is all I'm capturing on this target for now.

Description: Complete rework using an inverted L mask with a low pass frequency filter for NR in the background and an edge mask with high pass filter for sharpening the galaxy spirals. This was primarily a practice using a couple of new techniques I'd learned (or trying to learn).
