Composite image of a USA 161 pass

Below image is a composite of two 10.7 second images, 35 seconds apart, made during yesterday's USA 161 (01-044A) pass. It includes the flare image posted earlier.

The stitch of the two images was made with Hugin/PTStitcher, the same software I use for my daylight panorama images.

The flare effect is even more accentuated in this composite, and the wide angle (roughly 50 x 50 degrees) makes several constellations well recognizable.

The glare in the lower right corner is reflection from a lamp on the courtyard.

(this image is of course reduced in size and compressed compared to the original, hence the fainter stars are lost).
