Trixie gets the laser test
My astro-Jedi friend Art came over to kick Trixie’s tires a little. He brought a laser, did a rough collimation, and then hung some weight off the focuser (in the form of […]

Trixie comes out of hibernation
When I left CA, I had just finished doing a pretty major rebuild of Trixie, which as you recall is my attempt at a 13″ Newtonian Astrograph. The newly-trussed frame seems very […]

Still trying to get the observatory computer working
So after much gnashing of teeth and tearing of hair, I figured out that it’s going to be next to impossible for me to get the rig up and running fully in […]

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 […]

Dome shutter is motorized again!
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 […]
