I’m learning and experimenting with the camera and processing software mostly for the purpose of using it for variable star photometry.
The following was taken on Dec 21 2014 with a USM 100mm EF f2.0 lens piggy-backed on a Meade LX-90 telescope in alt-az (vs equatorial) mode. Click to enlarge.
There are plenty of better images of the comet taken by others of course, but this is mine. 🙂 I plan to take more images in the coming days as the comet brightens.
