Sean and Malcom, you guys are amazing. I know what the problem is. I took my flats before the imaging session and must have left the filter on for the flats. I later realized that I had forgotten to remove it, but by then I had forgotten about the flats and it never even came into my mind that the flats were inaccurate calibration frames. The inaccurate calibration was made based on the L-Extreme's pretzel looking pattern on the sensor. I just re-processed without the flats and got the image below.

Any ideas on how to get rid of the reflection though? I think it's from a nearby street lamp. Other than the obvious of imaging further away...?
