MDM Trouble Report for 2018 Nov 01

Telescope: 1.3m
Observer(s): Weil & Podjed (Dartmouth)
Instrument: Echelle

Problem(s) Encountered:
Beginning of the night had problems pointing and accurately
finding targets. In order to determine position, pointed to 
a bright star and uploaded the image to nova.astrometry.net 
to determine the center of the field coordinates. We then
reset the telescope coordinates to reflect these coordinates. 

The telescope then lost pointing within an hour and this 
procedure had to be repeated once more. After this point, 
the telescope pointed without incident for the remaining 
8 hours of the night. 

At the end of the night when the telescope was pointed to 
the zenith the tip tilt sensors read: E/W -003 N/S -014,
although pointing previous to this had left targets centered
in the field of view. 

In addition when pointing into the East at HA>3, the stars 
appeared elongated along the East/West direction. If the telescope
was then pointed back slightly to the West even at HA>3, the stars
no longer appeared elongated.
