Image Description:

IC 1287 is a very faint reflection nebula in Scutum. In this image it is just barely visible as a blue "halo" around the bright star in the center in the field (SAO 161569). This image could have used more exposure, but tracking problems ruined most of the frames I shot. The transparency and seeing were pretty lousy too. Those diffraction spikes look cool, though, don't they!? <g> This is approximately 2/3's of the full frame, scaled for display on the web. North is up.
