Well after 10 years my Boltwood has started to bite the dust. It seems it can not accurately read the sky temperature as it seems the sensor has gotten etched over the years. At $1,850 I'm looking for a more cost effective way to protect my observatory equipment. I see Stan Ralf has the AstroAlert system at $455 and AAg has a system, not sure on cost, but I'm looking to see what others are using and get recommendations as I'm in the process of setting up Scheduler and would like to be sure it can operate at maximum efficiency which I don't see possible without good weather data. So I'm looking to see what others are using successfully.

Thanks,
