Description

Well this year it bit me and I really wanted to make a solid M8 image. The difficulty being that it only rises to about 10-12 degrees above the horizon in Germany. Despite all this craziness I wanted to try it. To be honest with you I had to fight with the data for a long time. I think I'll just leave it be for now as I won't get more/better data this year. So this is it then and I humbly present to you my attempt at making a good image out of it. To save my sanity I will try and stay away from low altitude targets for a while :D
