NGC 6791 in Lyra


Scope: C8  f/2.8; Location:  Del Mar CA;  30 Oct. 2004; Camera: ToUcam SC3

Exposure: 24 x 6 sec  Luminance exposure with Baader IR Block Filter; 16 x 8 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.  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 an unguided exposure. This was a quick image of an object that had caught my interest. This cluster is said to be one of the oldest open clusters in the Milky Way Galaxy.   Horizontal FOV is about 30'.
