Also used a Baader contrast booster filter as the telescope has very bad
chromatic aberration. Images were taken in Bedford (England) looking south
over the town with bad light pollution. 15 out of 89 frames stacked (others
deleted as the telescope mount/drive is not very good and there was bad
trailing on most frames due to inaccuracies in the drive train).
