I did a 200 point model yesterday with my new AP1100 yesterday
while the moon was out. It dropped to -30C. It was very
effective with an average duration of 35 sec / point and no
This improved Guiding and pointing accuracy.
However, the temperature was so cold that the mount was
squealing - see video. I had max slew speed set to 900. I can
understand the motors making more noise as they work to overcome
higher viscosity. But there is also a sound which appears to be
of resonance - I wonder if the worm mesh is too tight. I had a
similar sound on an IOPTRON mount which I resolved by loosening
the gears-worm tightness.
Any advice on whether I need to do anything would be
appreciated (I realize that this is very cold and would require
different grease etc)
