Which way is up?
I spent the night polar aligning the NJP. Man, I love the sound of the mount as it slews. It’s… hard to describe. The polar scope (and its attendant app) got me […]

Fits and starts
As with any new piece of gear, the NJP is going to take a little work to get it up and running in the observatory. I knew that I was going to […]

Mac vs PC for astrophotography

Bob’s Knobs
I spent a long time collimating Veronica the other day, with the new autocollimator I bought. That experience convinced me to buy Bob’s Knobs for Veronica and Cassie. I knew I would […]

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 […]
