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'.
