Hi All,
You can also use binocular eyepieces in 1"/1/4 focusers by buying some 32mm light weight aluminium tubing,you will have to turn down the outside of the tube a little as it's a little too big as it comes.
Simply cut the tube to length,Araldite the eyepiece in the top,and you have a very cheap eyepiece.
I bought a pair of tasco 7x35 binoculars off ebay,which had an 82 deg fov,
ie, 620 feet at 1000 yards =620/52.5 = 11.8 deg x 7x mag= 82 deg fov.
the focal length of most binocular eyepieces varies from about 18mm to about 22m.
They eyepiece is certainly no Nagler,but is good on m42 for eg,and other wide views.
The other half of the binocular becomes a 7x35 82 deg finderscope.
Regards.John
