Trixie 2017 and 04026 — Together again
The skies cleared a little just at dusk today. It’s been raining hard for several days, I wasn’t ready for any sky tonight. 4th NJP counterweight was in the travel gear from […]

NJP Power up
My mount, 04026, and I have had a pretty good run together. I had to swap out the motors and brain a couple of years ago, when the main motor controller board […]

M42 gets the Plate-Solved treatment
Oh, it’s starting to get fun, now. The dome is ludicrous, but it works. I set up SGPro for a series of 20m subframes. All guided and focused and stuff. The next […]
Trixie takes a test drive
It was a gorgeous sunny day today in Seattle (very strange for mid February), and the clear skies held up until nearly 11pm. Kismet or dumb luck, I knew that this was […]

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 […]

NJP – oh, so *that’s* the problem
The NJP can GOTO again! Art and I spent some time diagnosing and then fixing the problem, which turned out to be an unplugged Dec encoder cable. Now that the mount is […]
Prosthetic limb for the mount
The NJP doesn’t like high northern latitudes. Because of the way the altitude axis is adjusted, if you live north of about 40º latitude, you start being unable to adjust the mount […]
Trying to get back under the stars
It’s been a long time since I’ve had the telescope out. I’ve considered selling all the gear and picking up some other hobby. Between spotty access to clear skies, a new latitude […]

NJP maintenance – getting my shed together
The NJP’s state when it got back from “repair” was pretty sad. I mean, even a poorly working NJP is better than I’d ever really gotten with the G-11, but it needed […]

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 […]
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 […]
