Soon, Trixie. Soon.
Because I’ve made so much progress on the observatory of late, I was looking over my Bookmarks, to see if anything needed updating. Trixie (look in the tag cloud) is on-hold right […]

Star Trails over Ad Astra Observatory
It’s been awhile since I did any star trails photography. It’s pretty simple — camera, tripod, point it at your target, and let it rip. I figured this would make a handsome […]
A change at QB for Hilltop Observatory
Well, it happened again. The dawn of a new era in Hilltop Observatory. Today, the new imaging camera showed up in the mail. I bought it from Renaud Venne Landry, one of […]
Alas, mostly cloudy.
Third night in a row in the observatory — it was pretty cloudy tonight. Suckerholes all night and all over. I had a visitor — my neighbor has been showing an interest […]
Deep Sky / Long Exposure Photography
Another beautiful night.
I stayed up way too late on First Light night, but the sky was clear again the next night, so out I went. I did a little testing to start the evening, […]

Final First Light photo
I finally got through processing all the images from the first few nights of shooting. The workflow is very slow, and I am using unfamiliar tools, but it’s starting to come back. […]

Trixie trials
Clear nights come about once a week right now. It was suckerholes until about 9pm and then clear until about midnight. I spent some time collimating everything. First, I collimated Trixie, which […]
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 […]

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 […]
