MDM Trouble Report for 2012 May 29 Telescope: 2.4m Observer(s): John Thorstensen (Dartmouth) Instrument: Modspec + Templeton Problem(s) Encountered: A few glitches: The Andor Solis software seemed to hang a few times; restarting the program solved this. I did save a couple of pictures to document slit placement; this generated some griping about Maxim DL (I think it was trying to open the images with that utility) and I wonder if this had anything to do with it. Rotator died once, solved by power cycling. You need to leave it off for something like 10-20 seconds before it clears. At the end of the night, the shutter failed; I was almost done anyway, so I closed up. When I did so I saw that the shutter control box had fallen off and was hanging by its power cord. The shutter failure is not particularly surprising, then. If this had happened earlier, I might have tried to fix it, but it was too late to do anything at that point. ------------------------------ Submitted on 2012 May 30 [5:12:46]
