Andromeda Galaxy (M31)

The "problem" with imaging galaxies is that a lot of them occupy only small areas of the sky. They may be HUGE objects, but for many of them, their distance makes their apparent size in the night sky very small. That, however, is not the case with the Andromeda Galaxy. It is one of our closest galactic neighbors, but is still 2.5 million light years away. Given its size (approximately 150,000 light years across) and relative close distance, if you could see the whole galaxy in the sky with your naked eye, it would be about 6 times wider than the Moon when it is full.

I've recently added a Ha/OIII narrowband filter, and I'm working on adding Ha to this image via a Continuum Subtraction process. It's getting there, but I think I need more NB time on the target. There's comparatively little narrowband signal when compared to broadband, so it'll probably take a few more nights.
