NGC 2506 in Monoceros

 

Scope: C8 f/5;  Location:  Del Mar  CA;  8 Feb. 2005; Camera: ToUcam SC3

Exposure: 15 x 36 sec with Orion Skyglo and  Baader IR Block Filter and 24 x 12 sec with Baader IR Block Filter for Luminance exposures; 18 x 12 sec R,G,B exposures.

Processing: All exposures captured  in K3CCDTools 2. Alignment and stacking was done with Registax 3 and saved as FITs. LRGB channels were co-registered in IRIS. Luminance and Color channels were scaled and rough color balanced in IRIS.  The  luminance exposures was constructed with the with the 36 sec exposure; the 12 sec luminance exposure was not used. 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 a guided exposure. NGC2506 is a small (visually), moderately old open cluster. Its age accounts for the star colors to be more toward the red than blue. Located in the constellation of Monoceros. Horizontal FOV is about 16'.
