Description

Last year I was able to take M 81 with short time exposure with good seeing. The depth of the picture was quite good, the accompanying galaxy Holmberg IX was well capured. Above all, however, I wanted to use the high signal-to-noise ratio in the centre to make as many details as possible visible. The section of the Hubble-picture for comparison is of course reduced in size.

AOM 160/1600 x 0,75 5.05.2018 L = 1.047 x 4,5 s = 4.711,5 s
APQ 130/1000 x 0,75 18.04.2018 L = 210 x 25 s
und 19.04.2018 R = 99 x 25 s G = 99 x 25 s B = 86 x 25 s
