Description

Was unlucky to obtain more images for the Hα channel, it started to rain overnight (and the telescope stayed out there, yikes!) so that I got only 9 sub frames. Hence the image resulted a bit more "blueish" than I wanted, although the Plejades should always be "blueish" :-), it somehow fits to it. There is still enough time this year to improve.

Green = 50% Hα - 50% OIII
