This image of comet 17P/Holmes was taken last night using my 70-300mm lens with the camera mounted on the front of our Spacewatch 36 inch telescope - in essense, using our big telescope as a glorified guide scope. This image was taken at 92mm focal length with an exposure of 2 minutes at f/5, ISO 400.

I knew that you would use your 36"! Awesome widefield!

Comet is just to touch Mirfak!

Thanks Tuggii. I took some more last night, but have to head home today. It was hard to adjust the camera on the end of the telescope between the limitations of the tripod head the way it was mounted and the location of the viewfinder and LCD display and the looseness of the tripod foot on the camera. I was lucky to get anything. Ah, the advantages of a small backyard equatorial mount....
