MDM Trouble Report for 2018 Jan 07 Telescope: 2.4m Observer(s): Rupert (MDM) Instrument: OSMOS/B Problem(s) Encountered: The B4K or related electronics seems to be on the fritz. Regardless of the type of exposure (dark, comp, etc.) the readout of the camera is three quadrants with pixel values of around 420 in ds9 and the fourth with values around 7200. I messed with the connection between the HE and the camera to ensure it was truly connected, as this has been an issue in the past. I also power cycled the HE. My final test was to leave the HE powered down for several hours and let it cool down (even though it wasn't particularly warm) and try again, which also failed to work. ------------------------------ Submitted on 2018 Jan 8 [0:46:58]
