MDM Trouble Report for 2014 Dec 28

Telescope: 2.4m
Observer(s): Jules Halpern,  Adrian Lucy (Columbia )
Instrument: OSMOS

Problem(s) Encountered:
I suspect that the filter table in OSMOS is wrong because the
slot listed as having the B filter is giving way too many counts
and fringing in the image, which leads me to believe that it is
an open position.  Rather than waste time at night investigating
this, I am switching back to doing spectroscopy, because I haven't ever
looked inside OSMOS before. I could probably just take the cover
off, but I would prefer if someone would call or point me to
instructions about how to check the filters.
