To enable temperature of regulation of the primary mirror I have designed and printed a fan mount. The fan is controlled by ArDewNo and serves a few purposes:
- Bringing the temperature of the mirror back up ambient when it drops below.
- Preventing and removing condensation.
- Cooling the mirror at the start of the session.
- Breaking up the boundary layer effect.
I have also printed an outer ring that acts as a stand off with a 5mm slot for the fan and temperature sensor cable to pass. This protects it from being crushed when the telescope is stood upright on the floor.
