Fascinating! Looping in fellow astronomy enthusiasts @anna , @astronomerritt , @nyrath and @isaackuo ... and everyone I forgot!@DenOfEarth @liamvhogan @anna @astronomerritt @nyrath @isaackuo Variants on this approach were fairly standard in large telescopes up until the mid 1970's when computer control systems able to do the required trigonometry digitally took over. Coincidentally one of the first examples of the latter was the Anglo-Australian Telescope, at the same observatory (Siding Spring) as the UK Schmidt Telescope and its phantom.
Numerous radio telescopes and at least some of the Deep Space Network communication dishes used what they called a Master Equatorial, effectively a model of an equatorial mount telescope being used to mechanically compute the required position for the real altitude-azimuth mounted telescope.
This is the Murriyang/Parkes Master Equatorial, which as far as I know is still in use: https://www.atnf.csiro.au/daily-picture/2017/09/11/the-parkes-master-equatorial/

@liamvhogan a classic of the there’s definitely a backstory genre
(To be fair the place where the sign was had the world’s chill-est kangaroos so I can sort of see the temptation)

@liamvhogan This one caught the kids attention at Yellowstone
@Michigander @liamvhogan
I was doing a field job years ago and we passed through Yellowstone a couple of times. We had a similar flyer taped to the dash but the person had a camera around their neck. We saw multiple candidates to be the next person on the sign, haha -
