Celatone

As some of you know, the Royal Observatory Greenwich is hosting Longitude Punk'd, an art exhibit featuring a steampunk take on the Longitude Prize and some of the less-than-practical inventions it inspired. Part of this was an open competition for entries, which I obviously had to enter. I mean, one of my favorite places on Earth, asking for works in my particular artistic niche, inspired by one of my favorite corners of history? If it was any more tailored to me, I'd be afraid it was a trap.

Part of the reason (I think) was to promote the archive of all the correspondence of the Board of the Longitude, and entrants were encouraged to take inspiration from actual proposals. After poking around, I settled on Samuel Parlour's 1824 "apparatus to render a telescope manageable on shipboard", which was itself a reinvention of Galileo's celatone concept. I bought an antique spyglass and a large chunk of brass off eBay, and started work in late December. The work went pretty fast, making extensive use of my new lathe. I'm comfortable saying it's my best work ever for a piece of this scale.

And... I just found out it was accepted. Sometime in April I'll be taking it to London, where it will go on display for the rest of the year. Along with, you know, the Harrison Chronometers. In Flamsteed House. On the Prime Meridian. I can't even begin to wrap my head around that. Remind me to keep putting in applications to ridiculous things. It works far more than it should.
