Regards from DS-Meet, a Deepsky observers gathering in Tähtikallio observatory in Artjärvi. Skies in Tähtikallio are very dark and I was after M31 again to get the most out of the galaxy. Weather wasn't the best during the happening but we had a short window of clear dark sky (21.37mag/arcsec2) and I could do some imaging. I was prepared to expose til the dawn but those clouds... Anyway, I think I got still a nice image - but I still have to return to this once more to get my planned 4hrs of exposure and try to reveal the material bridgw between M31 and M110.
