he finetuning rings are 2" OD and threaded M48 (filter thread) on each end, so they can be installed in-between the Hyperion's removable front negative element and main body, simply install it between the front element and the main body of the eyepiece, this additional spacing increases the focal length thereby increasing magnification.
Please note that Baader 24mm Hyperion Eyepiece will not accept the Fine Tuning Rings due to a difference in optical design.
