2013 comet Panstarrs on 13 March 2013

Mike Mattei and I set up on Nagog Hill in Littleton, MA.

We took this image with a Canon 40D, 135 mm setting on a zoom lens (28 mm - 135 mm) on 13 March 2013, at about 19:50 EDT (18:50 EST) (23:50 UTC).

The image was stretched by Photoshop to adjust brightness.  The pesky aircraft contrail shows in the original camera image and also in the stretched image “with contrail”.  The contrail was painted out by the Photoshop clone tool, as shown by the “no contrail” image.
