NGC 2383 and 2384 in Canis Major


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

Exposure: 16 x 32 sec with Orion Skyglo and 24 x 10 sec with Baader IR Block  for Luminance exposures; 15 x 16 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 channel was constructed with the with the 32 sec exposure as the base exposure; the 10 sec exposure was not used.  LRGB channels were resized to 800x600 prior to LRGB combine. Final LRGB combine was done in Photoshop using Luminance Layering (or LLRGB). Color balancing and final touches were done in Photoshop (Blue halo subtraction and background noise subtraction). SGBNR (PixInsight LE) was used to smooth remaining background  on the final result. Final image size is approximately 800x600.

This image was a guided exposure. NGC 2383 is the cluster in the upper right and NGC 2384 is the cluster in the lower left of the image. These clusters are located in Canis Major close to the Puppis border.  North is up in this image.  Horizontal FOV is about 16'. 

Image center is at Equatorial 2000: RA: 07h 24m 52s Dec: -2058'38"
