Trixie the Dob – first light!
Well, nobody can say I didn’t pay my dues on this one. Between weeks of rain and countless trips to the hardware store, I think I earned myself a little starlight. After […]
Trixie the Dobsonian
Well, I finally completed the Dobsonian mount for Trixie. The idea is that I wanted to have a backup scope for use while the NJP is in use doing photography. I learned […]

Trixie Dob conversion — CNC parts laid out
I did a little bit of cleanup on the parts (I cut the rocker sides down and chopped the bearings in half, and did some sanding). Most of the rest of the […]

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 […]
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 […]
