Several things I should have done different here, but the mosquitos were killing my concentration. After 10 minutes or so I just wanted to get back in the house. This is with the Kenko 2x TC and the 70-300L. Tripod mounted, ISO 100, f11, 1/125 sec. If I were to become an astrophotographer, I'd invest in a geared tripod head. Setting the head to keep the moon centered is a royal pain.
