Comet P/2006 HR30 (Siding Spring)
Periodic comet P/2006 HR30 (Siding Spring) is currently in the constellation Cygnus. As you can see in the below image it is quite “asteroid-like” in appearance. I’m now not surprised that we couldn’t find it last week visually as we were looking for the customary nebulous head. Even though it is nearly directly overhead shortly after sunset, it is quite faint, vmag estimate is 13.9.
Images taken from Louisville, CO on Nov 26, 2006 between 17:59 MST to 18:04 MST and 18:15 MST to 18:19 MST. Telescope was Celestron Nexstar11, F3.3 focal reducer, and Astrovid Stellacam II video camera. Images were dark subtracted and flat field corrected with ImagePlus, aligned and stacked with Registax4.
