NGC6822 - Barnard's Galaxy


Scope: C8 f/4; Location: Laguna Mountains, CA;  17 July. 2004; Camera: ToUcam SC3

Exposure: 10 x 90 sec Luminance exposure with IR Block Filter; 10 x 45 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. Stars were a little tracked so the image was darkened with a duuplicate shifted one pixel (with star mask). Color balancing and final touches in Photoshop. SGBNR was used to smooth background noise on the luminance channel and the final result. Resized to approximately 800x600.

This image was a guided image. North is to the left in this image. This object is commonly known as Barnard's Galaxy. The planetary ring usually seen with this object can be seen in the upper left corner . Horizontal FOV is about 18'
