New tests with the DSI camera...

On May, 1st-2nd, I performed a few new tests with the DSI camera (thanks to Manuel who kindly provided to me) attached to my Newton telescope (6", f/5) and the CG5-GT mount. These are single-shot images (i.e. not an average of a number of individual exposures) and the dark frames were too short. While the quality is not very good (e.g. very noisy background), they're nice on average so I post them. Exposure times are: 60 sec (M51), 30 sec (M104), 60 sec (M81) and 8 sec (M3)
