Red Sprite

While not a great composition, this image shows a semi-rare and very hard to capture object - a red sprite. Red sprites can sometimes be captured (and very very rarely seen) when viewing a powerful lightning storm from its back side. Conditions need to be perfect in that the storm need to be 50-100km away, still very active, and the sky must be clear from the observer to the storm. Even then red sprites only last for about a thousandth of a second.
As I was framing my camera for a night of Perseid meteor imaging, this red sprite appeared in the corner of the vertical image. To make sure I captured what I thought I captured, I immediately took a second shot - this time the sprite was not there. Since the sprite was in the lower right corner of the image, I decided to reorient my camera and take a quick horizontal shot to show the lighting storm. This image a pano of the vertical shot containing the sprite and the horizontal shot of the storm.
