M88 in Coma Berenices



Scope: C8  f/8, Location: Blair Valley, Anza Borrego Desert, CA   4 March 2006  Camera: Artemis285

Exposure: 8 x 360 sec Luminance exposures with IR block, 8 x 120 sec (2x2 bin) RGB exposures.

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).  Selective sharpening with layer mask was applied to galaxy dust lanes.  Color balancing and final touches were done in Photoshop. SGBNR was used to smooth  background noise on the  final result. Final Image size is approximately 1392x1040.

North is up in this image. The image was guided for all exposures. M88 is one of the bright members of the Virgo cluster and is located in the constellation of Coma Berenices. It  is about 60 million light years distant from Earth. A Magnitude 16.6 galaxy (PGC169494) is visible at the lower edge of the field and an 18.7 Magnitude galaxy (PGC169501) is a fuzzy spec just to the left of M88.  Horizontal FOV is 20'

Image center is approximately - Equatorial 2000: RA: 12h 31m 59s Dec: +1425'11"
