Can't see a problem here ........

Actually yea I can.........

everyone knows not to stand your setup on decking it's just not solid enough


And that dangling camera strap is a disaster waiting to happen.....

I thought those mounts were taller than that, has it already gone through

There is an obvious explanation.
The back garden is clearly that of William. The tripod, the mount and the telescopes are all by William Optics. When they make a new telescope, William takes it home and tries it out - comparing it to all previous models. Simples!
