My original plan was to shoot Mars before he is too far away again, but the seeing was so bad and it was too windy for the big scope it made no sense. So I decided to switch to my Baby-Newton because he is very stable in the wind and image M31. It went well for about an hour, then the wind got stronger and stronger and at some point I had to stop. It didn't turn out so bad but I will try it again under better conditions. I need much more integration time and the stars are not very pretty because of the wind.
