Re. post #238.
I went through the items.
Firstly, the amount of old optics is amazing.
There are a few Bitsa telescopes. bitsa this and bitsa that.
A Kalimar/Glanz micro monocular 7x40 with 9.5 degree field Japan presumably with the objective removed and attached to the back of a telescope tube. Not a bad idea.
Then a 1/6inch Broadhurst Clarkson brass Huyghenian RAS thread eyepiece behind the rounded wooden back end of a telescope with an instrument maker's plate from North or South Shields.
The eye relief is minimal.
The prices of old optics are incredibly varied.
$15 million dollars for an old Leica camera recently sold, to this auction site where ten assorted binoculars can be bought for £20.
The amount of waste products human beings make is enormous.

B.
