The idea is to work within the +- .5 deg band.
I get my mirror about 1 degree under ambient, turn off the cooling, wait aprox 5 - 10 mins for the air to stop moving and the mirror to stop flexing......then i image until the ambient is .5 degrees under the mirror.
Moving air in the OTA will most certainly stuff the seeing.
If you get a c14, then peltiers will work a treat.... a c9.25, there is very little room behind the mirror and well for he c8... the fridge
