Hilltop Observatory Control Panel, thoughts on design
Here’s what I have: Here’s where I’m going with it: I know, not a big delta. I even have all the mointor-y bits working, just need to mount the screens and … […]
Finally got a second monitor working
The original design for the observatory included multiple monitors, each displaying some important telemetry or other. During the build process, I decided it would be cool to have these driven by Raspberry […]

Desk upgrades
I really like the observatory desk. It’s of a postwar-era “built like a tank” style that has always appealed to me, and the buttons and circuit board were 😮 (have I posted […]

Dome automation-0.2-alpha – Wiring up the sensors
When we last left the dome automation project, the azimuth encoders were fried. I had a working circuit on the breadboard. I wired the cable rolled from the original, and soldered it […]

Special Guest Star takes the mount at Hilltop O
The Astro Jedi needed somewhere to store his light sab—- I mean, bucket, and I was only too happy to accommodate him. I have decided that I need to come to a […]

I finally decided to bite the bullet and fix the shutter motor. Things went sideways last winter, and I’ve been opening the shutter manually (and tying it shut with rope, so we […]
Trixie 2017 – tube mods
I finally got around to cutting the MTA-UTA tubes to length; the only eyepiece that would come to focus with the focuser spacer in place is the Televue 55mm Plossl. If I […]
