Microscope Adapter ring Swift - M42

Edit new version 22 Nov 2021
made to take 23mm eyepieces tube length 160mm


Adapter ring for mounting a camera on the Swift polarizing microscope.

It substitutes the eyepiece holder; it has 42 x 1 mm male thread on top.

The inner hole has the diameter to hold astronomical eyepieces, 1,25 inches.

The microscope for which it fits is the old Swift polarizing microscope, with 34,8 mm barrel hole and a flange screw of about 46,8 mm, as from the photo. I don't knof if can fit other microscopes.
