The Andromeda Galaxy is the closest neighboring galaxy, a mere 2.5 million light-years away. It is the only galaxy visible to the naked eye - but just barely. The galaxy is made up of around 1 trillion stars.
This is our best picture of the Andromeda Galaxy so far. Weather was nice and we were able to use 45 of the 48 frames we shot. In the picture there are also two satellite (“dwarf”) galaxies of Andromeda.

Found a few old light frames about the Orion nebula. Even without darks, autoguiding, dithering or a coma corrector, this thing is still pretty awesome.
I have no idea why there were 87 bias frames next to the lights.
