On 20/7/06 I took about 5 widefield images of the area around Neptune. The first image I took had an 'extra' point of light on the first image. It didn't appear on any of the other 4 images. The image below is a crop from the first and second frames. The images were all 64 sec exposures.
I first thought it must be a hot pixel on the chip, but then surely it would appear on all the images and not just the first one.
Any ideas? UFO perhaps??
