At least that's what the instruction sheet calls it.
Turns screw mount Pentax lens into a telescope.

Sounds like fun. How is it different than putting the lens on a camera to
use as a telescope? More magnification?

More magnification - the instruction sheet says to devide the lens focal
length by 10 to get the power of magnification - a 300 mm lens with this
'viewer' will yield 30 power magnification.
