MDM Trouble Report for 2010 Sep 7

Telescope: 1.3m
Observer(s): Dietrich (OSU)
Instrument: CCDS

Problem(s) Encountered:
When I was observing Feige110 I wanted to improve the pointing
of the telescope. However, when reset tel.coord. I didn't check
that the current telescope coord. are indeed the current ones. 
The pointing was lost and when I tried to transfer the current 
coordinates, the telescope moved into a position that the tilt 
meter reached a limit. Tracking wasn't allowed anymore. Only 
with small steps in DEC it was possible to get out of the RA 
limits. Fortunately, Josh Schroeder from the 2.4m came over and
he knew how to increase the offsets which can be performed with
the paddle. Finally, the telescope was moved to zenith, the 
tilt meter display was set to 0.00 0.00, and with a bright star
the pointing was restored. - my fault
There was also some nodding of the telescope while guiding. For
short periods of time (2min - 3min) the telescope was nodding
in RA with an amplitude of a few arcsec and During another 
exposure telescope was nodding in DEC with a similar amplitude.
At the beginning of the night I failed to slew the telescope to
the position of 3C390.3 (error: pointing not converging
dist=66.357, dra=32.810 ddec=57.678). Hence, I moved to 
PG2130+099. After this object and about 90 min later it was 
possible without any problem to slew to 3C390.3.
