Dust features in NGC891
January 26, 2005
Two versions of a "visual" (V-band) image of the edge-on spiral galaxy NGC891, taken with the 3.5-meter WIYN telescope on Kitt Peak. NGC891 exhibits prominent dust-bearing clouds in a thickened disk of interstellar material. The left panel shows the direct V-band image; the right panel shows the same image after the application of an unsharp masking technique. Individual clouds, observable through their extinction of background stellar light, have sizes on the order of a few hundred parsecs.
