Hilltop Observatory – First Light
We did it! It’s been a long hard journey, with lessons learned, and ducks carefully put into rows. Four years of design and development all came together tonight. The sky was even clearer tonight […]
Sky 1, Trixie 0
Let us say that the night culminated in me recollimating my telescope at 1:45 am. That about sums up “how it went”. At sunset, there was a rather large sucker hole over […]

Observatory 2.0 – We control the horizontal and the vertical
The observatory just inherited two computers; the 2010 iMac from the house, and my old 2009 Macbook Pro laptop. Both of them had full hard drives, and needed a refresh, so I […]
Return of the Jedi
An exciting development! But first, the news. When we last left Hilltop Observatory, I had just gotten the encoder assembly hooked up to a dome wheel, and was thinking about how to […]

i got the DC power working a little better today. The 12v (battery) and 24v (power supply) are now under the NE corner eave, and they are supplying power to the dome […]
Observatory Status report
I got a bunch done in the observatory this weekend — I wired up enough outlets that I now have “wall power” all the way to the pier, including the desk area […]
Another week, still progressing
The march towards First Light is moving slowly, but steadily. I find myself torn between wanting to get things buttoned up out there, and knowing that it will be there for awhile, […]

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 […]
