NGC 6819 in Cygnus


Scope: C8  f/5; Location:  Del Mar CA;  1 Nov. 2004; Camera: ToUcam SC3

Exposure: 18 x 20 sec  and 18 x 6 sec Luminance exposures with Baader IR Block Filter; 15 x 16 sec RGB 

Processing: All exposures captured  in K3CCDTools. Alignment and stacking was done with Registax and saved as FITs. LRGB channels were co-registered in Astroart. Luminance and Color channels were scaled and rough color balanced in Astroart.  The shorter Luminance exposure was combined with the longer one to reduce star bloat in the Luminance construction. Final LRGB combine was done in Photoshop using Luminance Layering (or LLRGB). Color balancing and final touches were done in Photoshop. SGBNR (PixInsight LE) was used to smooth background noise on the luminance channel. Resized to approximately 800x600.

This image was a guided exposure. This star cluster is sometimes called the "Foxhead" It is difficult to see this image with this depth of exposure. As it is, the cluster is attractive and varied in color. Horizontal FOV is about 16'.
