Hyperion 2" Finetuning Stop Ring (with internal brass compression ring) is an additional accessory for the Baader Hyperion eyepieces. It is to be used when observing with a 2" mirror or prism star diagonal and prevents the 1.25" eyepiece barrel from hitting and damaging the mirror star diagonal or prism, whenever additional Finetuning Rings are lengthening the original eyepiece body. The second photo above demonstrates the combination of a Hyperion eyepiece, a 14mm finetuning ring, a 2" stop ring and a 2" diagonal mirror.
Of course, the use of this item is not restricted to Baader eyepieces only. It can also be used as a premium 2" parfocalizing ring with any brand of 2" eyepiece or 2" astronomy accessory. Features two large clamping thumbscrews for quick, no-tools hand use; virtually all other parfocalizing rings on the market use cumbersome set screws requiring allen keys for loosening/tightening.
