Description

Another from the (California) backyard - the Needle Galaxy! I've imaged this guy a few times before since it makes for a nice late winter/early spring galactic target for the large field-of-view of short refractor telescopes. Despite how big and bright it is, it was somehow missed by Charles Messier when he made his catalog.

The Needle Galaxy lies between 30-50 million lightyears away (a rather large uncertainty, actually) in the galaxy-stuffed constellation of Coma Berenices. It is actually a spiral galaxy that we are seeing edge-on, like looking at the side of a Frisbee.

Despite having nearly 19 hours of total exposure time, it still turned out rather noisier than I would hope. I'm finding the ZWO ASI294MC Pro to be a lot noisier than my 1600. A better one-shot color camera is somewhere in my future!
