This was my only attempt to capture Comet Leonard, an ad-hoc, last minute decision just under the wire!  Only got thirteen usable frames (30 seconds each), but with the EdgeHD and hyperstar, I'm very happy with the results.

I had really wanted to take a shot of Comet Leonard, but as the window for best viewing approached, the weather never seemed to cooperate.  Trees behind my house obscure the eastern horizon, and as we moved into early December, it was rising later every morning, leaving me only a few minutes before dawn when there was any hope of clearing the trees before the morning light made it impossible to see.

After missing one clear night because I was too lazy to wake up and set up the scope early in the morning, I really lost any hope of catching the comet on its approach toward the sun.  However, on Sunday Night, December 5, I set up the scope and left it out all night capturing several different targets.  I got up around 4:30 am to bring in the scope; Comet Leonard was still behind the trees, and I didn't think it would appear before dawn.  However, after tearing down everything and putting it away, I realized that there was one spot in the corner of the yard where I might be able to see the comet after about 5:15.

After much mental debate, I decided I couldn't miss the chance, however slim, so I set up my EdgeHD 925 with Hyperstar again.   There was barely enough time for a rough polar align, and APT didn't want to plate solve for some reason, so I manually thumbed in the coordinates and hoped the slew was accurate enough to get the comet within the field of view.  About 5:30 am, the first image came in:  I was shocked and pleased with how bright the subs were even with only 30 second exposures!  Surprisingly, PhD2 tracking worked directly on the comet's core (not sure if I even needed it), but I was able to capture continuously for over 20 minutes, until the light of dawn washed out everything.

I processed the image with PI CometAlign process, and it worked surprisingly well, given that I could clearly see the comet moving relative to the stars in each subframe.  Also, I didn't bother to remove the Dual band HO filter which was in place, but the greenish color seems to be comparable with a lot of the images I've seen of this comet.
