Problem:This object did not move very much at all during the course of a 600sec exposure. In a single image it appeared as a slightly elliptical star. Over the course of 4 images, however, its motion across the sky becomes noticable. This is a summed image of 4 600-second images showing the asteroid trail. Other smaller streaks visible in the image are just cosmic ray hits. |
Fix:If the asteroid actually passes over a target object, take another exposure. |
An asteroid closer to Earth or high satellite?
