Hello All,


I'm nearing completion of the outside work on the observatory, which means I'll start to put the electronics inside shortly.
These photos show the weather sensors to open and close the roof as needed.

I made an automated cover with a windscreen wiper motor to shade the all sky camera in the daytime as the camera sensor gets very hot in full sun. It's tinted acrylic, and I may put some window tint on it if necessary. The cover is on a schedule in time with the sun up and down. It's switched by a single pole double throw relay with power going to the motor all the time depending on which way the switch is thrown. At the motor, there is a single pole double throw toggle switch which is turned on and off with the cam on the motor shaft. This means it can always start it self.

Also up there is a Hydreon rain sensor that is a backup to the AAG cloud watcher if it fails to close the roof in a rain event. I have run water tubing to wash the sensors and all sky dome periodically of dust etc. The washer motor is bellow the tank so its alwsys primed. All electronic cables are covered in flex conduit and heatshrunk together for water tightness and bird proofness😂 Cables from the sensors are ducted through the frame and into the observatory that way.

Other things include an air cleaner to clean the air before it's pulled into the observatory by the fan, the Yagi directional antenna for cell signal and a couple of security cameras inside and out. The inside one has a microphone so I can hear what's going on if necessary.


I have some numbers and photos for you Paul in regards to the seels and brush.


Thanks for looking!
