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: -20°58'38"
