Fireworks Galaxy NGC 6946 and open cluster NGC 6939 in the constellation Kepheus. The galaxy is about 22 million lightyears away, NGC 6939 about 4000 lightyears. There is a faint signal of the dim galaxy PGC64824 visible at 5 o'clock . NGC 6946 is not an easy target (at least for me
). I also had tried to catch some Ha-data with the 12 nm filter to get more definition in the galaxy as long as the moon was above the horizon but that was not successful - the signal is obviously too weak for my setup.
