Edge On Spiral in Draco

Uploaded 4/2/02

A classic edge on Sc spiral, this object displays the dust lane detail and yellow coloration so splendidly seen in galaxies viewed in this aspect. NGC5907 is 11.1 magnitude, and spans a huge 13 arcminutes in length, filling the diagonal of the CCD field. I rotated the camera such that the object would fit if north was to the left here. Seeing was a bit poor, but there is plenty of detail in the dark dust filling the central region. The Wray Atlas shows a sunshine yellow spear of light, with a few blue regions in the outer arms marking stellar associations.
