NGC 663 in Cassiopeia


Scope: C8  f/2.8; Location:  Del Mar CA;  1 Nov. 2004; Camera: ToUcam SC3

Exposure: 20 x 12 sec  and 16 x 3 sec Luminance exposures with Baader IR Block Filter; 15 x 12 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 final result. Resized to approximately 800x600.

This image was an unguided exposure. This cluster is a relatively young open cluster populated with young blue stars. This cluster has a number of so called Be stars - link here to find out more Horizontal FOV is about 30'.
