tested new finder (Blue Mountains)

I built a new Sun finder for the Oberwerks big binoculars. Used a toilet paper tube! White paper screen at the end. No markings this time.

It worked!

It should not flex or collapse like my first attempt.

Spotted sun spot group 2586! It was tiny.

Could not see 2581. Turning away, perhaps?
