Canon eos eyepiece adapter

An adapter for Canon EOS camera the fits to the 1.25 inch eyepiece holder.

The smaller variant has a radius of 1,25 inch. This is probably the variant of this adapter that would be the best option for a normal telescope.

The larger variant is designed to fit A poor man's refractor telescope. If you use the larger variant, then you will need to apply a lite bit of force to push the adapter into the eyepiece holder which than will result in a stronger connection between the camera and the telescope.
