Celestron 9.25 EdgeHD SCT - Thermal Management

In the latest video, I have wrapped the OTA in nearly an inch of insultation and installed 40mmx40mm fans and 3d printed a fan unit for the telescope. Initial testing is very promising with no dew forming on the corrector plate. • PLL Ecco 2 environmental controller measured outside temperature • On the night, outside temperature was 7.9*C • The dew point was 3.9*C • I set the PLL manager to kick in 3.3*C above the dew point (on this occasion that translated to 7.2*C • The dew heater kicked in at 7.2*C and heated the corrector to 7.4*C and cut off • This means the dew ring does not run all night #telescope #nightsky #nasa #astrophotography #astrophysics
