Comet 17P\Holmes captured as LRGB with a DSI Pro II on a Williams Optical 66 APO guided on a LX200 10". Frames were 92 15s LUM and 14-16 15s RGB. Images stacked in ASIP using median combine. Color images was also assembled in ASIP and final processing done in Photoshop CS. A flat equivalent subtraction layer was produced by using the clone tool and Gaussian Blur. This subtracted from the initial image to remove much of the halo. 11/10/07
