Pietrabbondante
afternoon after a long reflection on the subject of shooting I choose this galaxy for two reasons ... because I saw it and why it is in an area very rich in galaxies. In addition NGC7331, main subject in the frame will many other small galaxies, among them also Stephan's Quintet. The subjects are very weak and deserve a more dark sky .. ... and many many poses even more experience ....
