Taken with an Baader Ha filter during a not so clear night.
If you look careful at the full size picture, You will notice at the border of the nebulosity of C443 and below the star Propus a small trail. I do not think it is a remain of a plane nor an artefact form the camera. I checked a few asteroids, but I cannot find any match. Anybody an idea? Pictures were taken from 21:26 till 01/32 CET.
