Right now it's very easy to control. There's only 2 planets worth shooting (Saturn & venus) in the AM which gives you plenty of time to setup just after dusk, point the OTA corrector down, bung in a cheshire with 3 winds of flywire & a rubber band around it to allow heat from the mirror to escape, tarp her up & walk away until 2AM.

It gets more difficult as the object becomes a PM object.

The flan blowing on it works wonders too. I keep my OTA in the shed with a big fan blowing on it 24/7 when not in use.

I have more trouble with seeing, more so than I'll ever have with not being at ambient. Once you've seen really good seeing (8+) even WITH internal thermals you'll wonder what the fuss was all about.
