Edge on Spiral Galaxy in Andromeda

Uploaded 2/5/01

The dust in this spiral seen edge on here causes both the dark dust lane across the middle, and tints the entire visible galaxy strongly yellowish. The Wray Atlas of Galaxies gives the B-V index of .92, which is strongly yellow for a galaxy. The faint two stars about an inch and a half to the lower right of the nucleus that point back at the center of the galaxy are magnitude 15.5, and are separated by 5.5 arcseconds. Although the tiny elliptical galaxy just to the upper right of the nucleus is anonymous, the faint inclined spiral to the upper left along the galaxies edge is ZOAG 140.39-17.38.
