so what do you do when its all cloudy or there is a full moon or whatever?
well you submit a job request to the Bradford Robotic telescope and a few days later they will email you to tell you the job is complete and you can download and have a play
just a bit of fun, you are are not getting a high quality image but ..its free! and you dont even need a telescope to get into astro imaging..or image objects in the Northern hemisphere
