The Tellurium went much more quickly thanks to what I learned on the Planetarium. One problem is that the manuals that came with have erratum sheets, which I didn't immediately see, and in fact the Planetarium has an erratum sheet for its erratum sheet! Gads. But I have confidence I've these two set correctly—with in 72 hours of correct. Come New Moon in three days and I'll have 'em spot on.
I may rest on my laurels for a bit. The Astrolabium looks to be a nightmare to set in comparison. I'm guessing 3-5 hours...
