Problem:Yet another example of an airplane going through the field of view during the exposure. In this one, it is obvious to see how airplanes are out of focus in images taken with astronomical telescopes. The two "tire tracks" going through the image on the top and bottom are most likely lights which are always illuminated, whereas the three doughnuts towards the center of the images are the strobe-like lights on the bottom of the airplane. |
Fix:None. Take another exposure. |
