M76 (Little Dumbbell) in Perseus


Scope: C8  f/10 Location: Dos Picos Park - Ramona CA   10/18/2003  Camera: ToUcam SC3

Exposure: 18 x 25  sec and 14 x 100 sec Luminance Exposure with IR  Block filter.  8 x 10 and 8 x 50 sec RGB Exposures

Processing: Captured  and stacked in K3CCDTools  with IR,R,G,B saved as FITs. Luminance was the IR exposures. LRGB masters were co- registered  in Astroart. Some Lowpass filtering was applied followed by un-sharp mask on the Luminance frame. LRGB combine was done in Photoshop using Luminance Layering . Background was smoothed in SGBNR as saved as TIF. The result TIF had minor touch up in Photoshop.

This image was taken in Dos Picos park in Ramona. I found M76 a small, dim, and challenging object. It is one of my few Deep Sky images taken at f/10. It was a guided image since this is a fairly narrow FOV. Horizontal FOV is 8'
