Scope: C8 f/5; Location:
Blair Valley, Anza Borrego Desert, CA; 7 May 2005; Camera: ToUcam SC3
Exposure: 16 x 80 sec and 16 x 24 sec Luminance exposures with IR Block Filter;
12 x 60 sec RGB
Processing: Images were captured in K3CCDTools 2. Aligned/stacked in Registax 3 and saved as FITS. Luminance and Color channels were scaled and rough color balanced in
Astroart. Channels were co-registered in Astroart. LRGB Channels were
resized to 800x600 prior to LRGB combine. Luminance and Color FITS were combined in Photoshop with Luminance Layering.
The shorter Luminance exposure was mask combined to reduce bloat in the brighter
stars. Color balancing and final touches in
Photoshop (including background noise subtraction on the Luminance master). SGBNR (PixInsight LE) was used to smooth
remaining background noise on the luminance channel. Final size approximately 800x600.
This image was a guided image. NGC 2997 is a spiral galaxy located in the small
constellation of Antlia at a rather Southerly declination making it difficult to
access even for my lower mid-Northern latitude. Horizontal FOV is about 16'
