I've got 2 of the TeleGizmo 365's and they are great. My setup is a permanent pier with a Paramount MX on top and most of the time that's all. That configuration has had a TG 365 on it for a long time now
but I have a medium Dew Strap around, and towels over, the MX to help control the condensation. For those multiple clear nights, I too, leave the OTA etc. set up and a different TG 365 over the lot. I'm in a rented house so anything more protective is not possible
