About this product

Model:  ae_parfocal_rings_1.25

A set of machined aluminium Parfocalising Rings to fit cameras or eyepieces with 1.25 or 2" nosepiece. 

Slip one over the nosepiece then lock it in position via it's grub screws. An Allen key is included. 

Useful for setting an imaging camera and eyepiece at the same focus point. You can then centre an object in the FOV using the eyepiece, swop it for the camera, tweak the focus and you're done. 

Similarly you can fit them to eyepieces then swop between them with minimal refocusing required. 

Note: These Parfocalising rings might not seat well if the nosepiece is tapered or has milled safety undercuts.
