Comet 17P Holmes on Nov 8
Comet 17P Holmes continues to amaze us all. It has grown a lot, its now about double the size it was a week ago. FOV in below image is about 28 for 43 arc minutes — so its now around 25 arc min across.
Image taken with Celestron Nexstar 11 telescope, F6.3 focal reducer, and Canon Xti at ISO1600 and 30 sec exposure. Registax4 used to stack and align 16/20 images. Resized and slightly enhanced with Photoshop CS3. Sky was clear, very good transparency, no wind, temperature 57°F, turbulence 6/10, and location was Louisville, CO.

No, too much light pollution here for that. I may head to the Pawnee Grasslands tonight for some dark sky. Not yet sure whether to go or not, forecasts are iffy for this evening.
View of comet Holmes is amazing in 10×50 binoculars, a bright fuzzy ball that is immediately obvious. View through larger scope in light pollution not as good, the comet covers nearly the entire field even at low power and lacks contrast so it is hard too see at first. Shows nicely with time exposures with camera and focal reducer though.
