M104 Sombrero in Virgo


Scope: C8 f/5; Location: Culp Valley Anza Borrego Desert, CA; 13 Mar. 2004; Camera: ToUcam SC3

Exposure: 20 x 60 sec Luminance exposures with Baader IR Block Filter; 8 x 60 sec RGB 

Processing: Images were captured in K3CCDTools. Aligned/stacked in Registax and saved as FITS. Luminance and Color channels were scaled and rough color balanced in Astroart. Channels were co-registered in Astroart. Luminance and Color FITS were combined in Photoshop with Luminance Layering. Color balancing and final touches in Photoshop. SGBNR was used to smooth background noise on the luminance channel and the final result.

This image was taken with fairly good conditions at a dark site. This is a guided image. This object crossed the meridian between the Luminance exposure and the RGB exposures. I was pleased to be able to cross the GEM mount over to the Western Hemisphere quickly and efficiently. Both image and guide cameras were dismounted in order to re-acquire the object and the guide star, but  I was exposing again within 10 minutes. Horizontal FOV is 16'
