MDM Trouble Report for 2018 Jan 10

Telescope: 2.4m
Observer(s): Douglas (Columbia)
Instrument: OSMOS/R

Problem(s) Encountered:
Both at the beginning and end of the night, after I filled the 
dewar, I was initially unable to disconnect the fill tube from the OSMOS
dewar. In both cases, I finger tightened the nut but didn't make 
it terribly tight, and at the end of the night, before I opened 
the valve on the storage dewar, I made sure I could loosen it again. 
But both times after the fill I had to use pliers to loosen 
the nut, even though I can usually disconnect the fill tube 
easily with just my hands. It also seems like the metal part of 
the fill tube is off centered from the metal connector to the 
rubber tube (if that makes any sense), which might be affecting 
how things screw together, but I couldn't re-center it
