NGC 2997 in Antlia


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'

Image Center is approximately Equatorial 2000: RA: 09h 45m 39s Dec: -3111'26"
