MDM Trouble Report for 2021 Jun 21

Telescope: 1.3m
Observer(s): Donghoon Son (SNU)
Instrument: Templeton

Problem(s) Encountered:
A filter wheel error occurred while the 1st target was observing.
Telecope position was Alt~45 in NW.

The 2.4m observer connected the RJ45 cable tighten.
However, the problem remained 
whenever the telescope slewed at low altitude (< ~55 deg) (in NW direction).

Although filter changed with no error massage at low altitude, 
it showed no star signal in the image (such as  bias) in any exposure time.
A filter I choose seems to not be at the correct position in the wheel.  
 
I observed only high altitude targets around Zenith (airmass < 1.2).
