After missing many clear nights while my equipment was in flux I've finally finished my automated observatory.  Willowed Plains Observatory, alluding to my youngest daughter Willow and the plains of the Midwest.  The odd design comes from a few design goals I had in mind:  The foot print had to be as small as possible while able to accommodate a 10" f/4 newtonian or 130mm f/7 refractor.  I did not want any support structure to extend beyond the footprint of the observatory while the roof is closed. And I wanted the roof to be able to close with the scopes in any position.  This precluded the much more common roll of roof which would have required much higher walls and would have reduced my horizon to about 50 degrees.  With the split roof clam-shell design  I've got clear horizon below 30 degrees in all directions.

This was quite a project.  Most of the time was spent in design and component selection.  The actual construction was probably 5 days of work and wiring.  I'm using a LunaticoAstro Dragonfly to control power to the PCs, scopes and for control of the roof.  The scripting, macros and relay/sensor safeguards that you can use make setup and monitoring very easy and robust.  I've paired the dragonfly with the AAG Cloudwatcher and a separate RG-11 rain sensor to ensure my equipment won't get drenched by sudden rain.  The entire observatory runs on 12v power supplied by a 35Ah SLA battery which is charged and maintained by a 5A tender/charger with another 8A 12v power supply connected through a diode to supply additional current should the actuators and other gear cause a voltage drop below 12V.  I've configured the dragonfly to be able to detect internet and power outages and to close the roof in either case.  Even if both PCs and my office PC were to all crash simultaneously the RG-11 will ensure the roof closes when it detects rain through the use of onboard macros.  I've also made an ESP32 based temp and humidity monitor to control a small heater and vent fan to keep high temps and high humidity under control, it can detect if the roof is open and will turn off both until the roof closes again.

With NINA I'll be able to fully automate imaging sessions and take advantage of short breaks in clouds and even image while I'm at work on the night shift.  Of course now that it is done we've had nothing but clouds and rain.

I've got plenty more pictures so if there is something you'd like to see I'd be happy to add it as a revision.  One of the revisions is a gif of the roof opening so make sure to check that out.
