NGC 5053 and M53 in Coma Berenices



Scope: Megrez II  f/4.8,  Location: Dos Picos Park, Ramona, CA   6 May 2007  Camera: Artemis285

Exposure: 12 x 180 sec  Luminance with IR Block Filter (bin 1x1); 8 x 90 sec RGB (2x2 bin)

Processing: Images were captured Artemis Capture (as FITs). Aligned/stacked in Registax 4 and saved as FITS. Luminance and Color channels were scaled and rough color balanced in Astroart. Central Gradient removal was performed in Astroart. Channels were co-registered in Astroart. The 240 sec IR block exposures were used as the main luminance construction with level adjustments and curves to bring out dim stars. Final LRGB combine was done in Photoshop.   Final touches were done in Photoshop.  PixInsight LE SGBNR was used for background noise reduction. Final Image size is approximately 1392x1040.

North is up in this image. M53 and NGC5053 are shown in this field. M53 is the bright globular cluster in the upper right; NGC5053 is the dimmer globular cluster in the lower left. ngc5053 is about 53,500 light years distant from Earth which is close to the distance of M53. This puts both globular clusters relative close to each other in space. A close up of M53 can be seen here. This wide field image replaces and earlier image that can be seen in the Archives here .  Horizontal FOV is 81'

Image center is approximately - Equatorial 2000: RA: 13h 14m 52s Dec: +1751'47"
