PemPro – Guido shows its power
PemPro needed some calibration before things would work today. Nothing major. I got it a little more dialed in. I finally figured out what it was complaining about — it thought it […]
FocusMax – Pumpkin is about dialed in
I was able to boot up FocusMax tonight and just go directly to “find star” and then “focus” and then “run 10 V-curves”. It had no problem finding a star, getting it […]
Clear nights coming in pairs now
It’s mid-March and I think that spring is finally starting to show some evidence of coming. The past couple of rain cycles, we are getting two days of clear instead of just […]
Decidedly odd weather
5pm, rain. 6pm, cloudy but “threatening” / drizzling. 8pm, serious hailstorm, lasted for an hour or so. 11pm, clear as a bell and (what looked like) steady seeing. 11pm is too late […]

Hazy shade of winter
It was not really clear out, and not for long, but it was enough to get some good stuff done. I got Guido focused and gathered a bunch of guiding data, including […]

Rainy weekend, perfect for maintenance
I had a bunch of maintenance piling up in the obvservatory, so I decided to do some of it since it’s raining all weekend. I spent a little time getting the mount […]

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 […]
