Looks pretty good to me H. The only advice I can give you is wrap your FSQ106 in dew heater straps and control the temperature with one of these

Fit the thermistor to the bulkiest part of the OTA ie near the front of the optic under the dew strap. These thermostats have an adjustable temperature interval to minimise hysteresis.
Set the temperature to just above ambient and wait for equlibration. Then focus and focus will NOT change even if ambient temperature drops by 20C!
I heat my 300mm lens this way at ALL times so it is ready to go. In winter it stops any chance of condensation as well.
Look forward to seeing what you can do with more time.
It is our job to try to understand our Universe. Astrophotography is one of the most masochistic methods.
