I've never heard of this before.
Great pics, number 2 is my fav.
I wonder if it's safe for pilots flying nearby? Will it reflect and concentrate the suns light at them?

Nah Nettie - although truly parabolic (apparently) it's built to focus just a few short metres in front of the surface. To a plane it's no brighter than glass windows on adjacent buildings.

Someone's got to get a big secondary, some framing / scaffolding and a cherry picker to turn it into a big, fast reflector.

It will be a bit limited in its range of movement but at least it will be put to something useful.

At 10m you wouldn't need any secondary. Just a ladder (that guy's cherry-picker would do!) and a good widefield eyepiece. Head-wobble could be a problem 'though.

Nice images Chris.

Heck, take a loooong fork and some snags, it would be a great solar BBQ !

Just wait till a chopper flies into the focal plane of that beastie on a sunny day like it is now...
Makes lasers look a tad puny

It looks really cool, well, hot....
No snags, but a couple of fried crispy seagulls.... It's currently scorching the earth about 10m in front of it at its focal point. Lol

Hehe the lawn won't last long... guess the museum people didn't think about the consequences of reflections !
