This is the Orion Nebula, as seen from my backyard. I know that focus and polar alignment can be improved. I have dabbled with PHD2 for polar alignment, but have not mastered it, and usually end up just eye-balling it (sacrilege, I know). Even still, I find it a fun challenge to find targets and collect data.

One interesting feature in this image is what I can only imagine is an artifact of my setup: the loop on the right hand side of the frame. I have not seen this in other images of M42, so I'm guessing it's some kind of bug in my setup. I'm not sure what though - it doesn't show up in my dark, flat, or bias frames. Any thoughts on that would be much appreciated!
