@liamvhogan this one was at Yulong Snow Mountain. The signs in China were always polite.

When did the North Pole become a desert? All roads lead to Hackberry Springs!

@liamvhogan and two gems from the fascinating genre of Singapore police signs. They don’t mess around with anti-crime communication
@joannaholman @liamvhogan @NewtonMark if you molest, we will arrest but if it’s a bit, we will acquit

@bassthang @liamvhogan I would have absolutely pissed myself if I'd found that while tripping. Where and why?

Good advice as long as you have that one remaining eye

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/
