NGC 300 in Sculptor



Scope: C8 f/5.8; Location: Blair Valley, Anza Borrego Desert, CA; 18 November, 2006; Camera: Artemis285

Exposure: 6 x 320 sec  Luminance exposures with IR Block Filter (bin 1x1); 6 x 120 sec RGB (bin 2x2) 

Processing: Images were captured in Artemis Capture (as FITs). Aligned/stacked in Registax 3 and saved as FITS. Luminance and Color channels were numerically scaled and  color balanced in Astroart.  Channels were co-registered in Astroart.  Curves and Levels applied in Photoshop to optimize object features.  Final LRGB combine was done in Photoshop using Luminance Layering (or LLRGB).  G2V color calibration  and Atmospheric Extinction  factors were applied to the color channels for color correction.  Selective sharpening with layer mask was applied to galaxy  spiral arms.  Due to low signal levels light background smoothing was applied to the luminance construction and the final result using PixInsight LE SGBNR and PS surface blur. Color balancing and final touches were done in Photoshop.  Final Image size is approximately 1392x1040.

 North is up in this image. NGC 300 is a galaxy located in the constellation of Sculptor. It is tight spiral galaxy that we view nearly face on.  It is difficult to view from my Northern location and best viewed in the Southern Hemisphere - it only rises about 18 degrees over my horizon in the Southern skies. The distance of NGC 300 to Earth is approximately 7.2  million light years. This image replaces and earlier image that can be seen in the Archives here.  Horizontal FOV is about 26'

Image Center approximately - Equatorial 2000: RA: 00h 54m 53s Dec: -3741'03"
