Baader Hyperion 2" Finetuning Stop Ring with Brass Clamping HYP-STOP Cat #2958027
Baader Item #2958027
Hyperion 2" Finetuning Stop Ring (with internal brass compression ring) is an accessory for the Baader Hyperion eyepieces.This is needed when observing with a 2" mirror or prism star diagonal. It 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.
