RA15_15 DEC55_55 NGC5907/5905/5908

Sedro-Woolley, Wa.

This is a 1 by 1.5 degree view in the constillation Draco centered at about RA15:15 DEC+55deg.55min. Celestial North is left and Celestial East bottom.
The largest galaxy is NGC5907 in the left part of the photo. To the right below center are NGC5905 with NGC5908 to its lower right.
Close to the top and right of center NGC5866 can be seen as a faint smudge.
The moon was full when this was taken and the image is contains more noise than I would like. Imaging time this time of year is reduced so I am lacking in exposures.
Smaller faint galaxys can be located in the full size image to about the sixteenth magnitude and stars are visible to about the 18th magnitude.
The brightest stars in this photo are about 8th to 9th magnitude, which are not visible with the naked eye, even from a dark site.
NGC5907 is about 50 million light years from earth, discovered by William Herschel in1788. It is said to be low in metalic content and is contains mainly dwarf stars.
NGC5905 is a barred spiral galaxy about 150 million light years from earth.
NGC5908 appears to be a spiral galaxy (because of the central buldge and dust lanes) also about 150 million light years from earth.
NGC5866B/PGC: 54267 I really couldn't find much info on this particular galaxy.
