M106 in Canes Venatici



Scope: C8 f/8; Location: Dos Picos Park, Ramona, CA; 15 March, 2007; Camera: Artemis285

Exposure: 8 x 330 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 4 and saved as FITS. Luminance and Color channels were numerically scaled and  color balanced in Astroart.  Channels were co-registered in Astroart.  Luminance exposure had central gradient removed 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   factors were applied to the color channels for color correction.  Selective sharpening with layer mask was applied to galaxy  features.  Color balancing and final touches were done in Photoshop.  A  light background noise reduction was performed on the Luminance channel using SGBNR in PixInsight prior to LRGB combine. Final Image size is approximately 1392x1040.

 North is up in this image. M106 is an bright spiral galaxy located in the constellation of Canes Venatici. M106 has active star formation that can be seen in the red regions of the spiral arms. The distance of M106 to Earth is approximately 25  million light years. This image replaces and earlier image that can be seen in the Archives here.  Horizontal FOV is about 20'
