Reprocessed an exposure from November 9 using fewer alignment points. Registax 5 was acting oddly when using multiple-hundred points: the quality setting didn’t match up with what I was seeing. I selected eight alignment points and at the completed alignment chose all 293 of 293 frames. This is a clip of the larger image so you can see actual resolution. Please note some angel-hair rays southwest of Tycho. The full size image is on the page: Third Quarter, November 9, 2009.
