NGC 5905 5907 5908 in Draco



Scope: Explore Scientific MN152 Maksutov Newtonian at f/4.8, Location:  Blair Valley, Anza Borrego Desert CA   10 May 2016  Camera: Atik 383 (Astronomik Gen II  LRGB filters)

Exposure: Exposure: 17 x 8 min, (1x1 bin) exposure with UV/IR block,  8 x 4 min (2x2 bin) RGB exposures.

Processing: Data Collection -  Sequence Generator Pro (as FITs).  Calibrated, stacked (Kappa Sigma Combine) Deep Sky Stacker, LRGB channel registration and equalization - Astroart.  Curves, Levels, RGB combine Images Plus. Luminance layering and finishing  - Photoshop. This image is an LRGB combine with Luminance layering. Color calibration - eXcalibrator. The Luminance construction was the Luminance exposures. Color saturation in LAB color.    Native image size - 3354x2529.  Final Image size is approximately 2800x2100.

North is to the right in this image. This field lies within the constellation of Draco. NGC5905 is the barred spiral in the left part of the image. Just above and seen edge-on is NGC 5908. NGC 5907 is the larger edge on galaxy on the right.  There are some smaller galaxies and more distant background galaxies in this field as well. These objects and some of the bright stars are identified in the annotated image.  Also interesting in this field is the double star system LDS 1422. One of the members is a white dwarf and the system has a  proper motion of about 369 mas/year. This is only about 3.5% of the proper motion of the famous "Barnards Star". However, it is a pretty significant motion considering this system is about 30 times more distant then Barnards Star. Horizontal FOV is 85'

Image center is approximately - Equatorial 2000: RA: 15h 14m 51s Dec: +5558'02"
