MDM Trouble Report for 2013 Feb 14

Telescope: 1.3m
Observer(s): Sarah Schmidt (Ohio State University)
Instrument: Nellie (imaging)

Problem(s) Encountered:
In the data I've been taking with Nellie, there's a circle in 
the middle with a diameter of 700 pixels where very little signal 
is coming through. I can't put my science target in the middle of 
the image, or use any reference stars that are located in those 
pixels. 

Because I'm a relatively new user and I could take data around 
the edges, I didn't try any sort of restarting/debugging, so 
hopefully this has a relatively simple solution.
