Despite the clear blue skies the seeing conditions were terrible in the unstable northerly airflow. I didn't think this image would come out, but it has! This was taken with the 70mm @ f12 and DMK31 using my CaK stack. I used a peice of KG5 in the optical train today which seems to have cut back on some of the bloomimng in the raw frame, next time I will try an ITF to see what impact this has.
