MDM Trouble Report for 2012 Nov 28 Telescope: 1.3m Observer(s): S.Lepine (AMNH) Instrument: R4K Problem(s) Encountered: All the images I took looked like bias frames, no counts. It seemed like the photons just did not reach the chips. Even internal flats yielded almost no counts except for what looked like light leaking near the edge. My guess is that the shutter would not open. Closing and re-opening Caliban, Isis, and Prospero did not help. No observations were obtained. Also, I realized that I had forgotten to ask for the SDSS-r filter, which I will need. It would be great if the filter could be installed in the wheel. ------------------------------ Submitted on 2012 Nov 29 [7:29:55]
