This is a very rarely imaged galaxy. I'm not sure why, because it is quite large (8.5' x 2') and bright. There are only three other pictures of this galaxy on IIS, two on Astrobin (both from IISers) and none on Cloudy Nights

This is probably one of the last pics I'll be taking with my trusty QSI through the Planewave, as the FLI Proline, Filter Wheel, MMOAG and Plane Wave connectors are all finally in hand. I'll probably use it on the Televue 101is.
Exposure details: Binned colour (3 hours), unbinned luminance (70 minutes), all 10 minute subframes.
Mount: AP900
Camera: QSI540wsg
Telescope: 12.5" Plane Wave CDK
I'll get in first and mention the warts in the background of the high res version before MS gets to say something
. Maybe a more careful reprocess is in order.
Very warm conditions, could only manage -10 with the QSI.
