Orion Optics ODK dewing

[jabberwock48]

Hello

I have taken the plunge and ordered a 14in ODK to replace my now sold Meade 14in ACF. I would be interested to receive any advice on keeping the mirrors dew free both when the scope is in use and at other times. My RoR observatory is in a small field in Cornwall and hence dew and dampness is common despite a dehumidifier.

I have taken the option to have Kendrick heater pads installed on both the primary (3) and secondary (1) mirrors during construction and the scope is fitted with fans as standard.

I am considering some scheme to keep the heater pads and perhaps fans running when the scope is not in use, perhaps with a thermostat to cut off the power when the observatory warms up. Any advice would be appreciated on how to best control the heaters and fans.

Regards

John
