Always darkest just before the dawn
The dawn of the NJP Age is coming. The mount is in transit, should arrive tomorrow. I have my fingers crossed that it will be a “drop-in” solution. I worry that the […]
8″ scope mods
I have several birds and several stones and I am thinking about applying the latter to the former in a particular way. Here’s what I’m talking about. Veronica is an 8″ f/5 […]

Mac vs PC for astrophotography
With the observatory down for another week or so, I have been considering re-trying the Mac Mini out as an observatory server. I started researching Mac astrophotography software, with disappointing results. Here […]

Ad Astra Observatory goes “dark” temporarily
Well, the mount upgrade is finally underway. The G-11 sold over the weekend, so the NJP will be on its way soon. What this means to me, of course, is that I […]
El Nino and mount sales during tax time

Bob’s Knobs

Trixie’s Last Stand
Trixie is listed on Astromart right now, probably won’t sell; who wants a project scope? I think once the dust settles from the new mount purchase, and I get my photography back […]
Thrashing about
I haven’t posted in awhile, and the reason is because everything is up in the air in my astronomy world right now. I have finally lost patience with the G-11, and have […]
Everything went right last night
FocusMax worked. PemPro worked. Guido worked. I shot M106 (through Pumpkin — tiny, tiny) until the mount hit the safety limit, 150m total or so. Then, since it was still clear (although […]

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 […]
