Baader Hyperion 2" Finetuning Stop Ring
Baader Hyperion 2" Finetuning Stop Ring
For Baader Hyperion eyepeice users, this 2" Finetuning Stop Ring with internal brass compression ring is highly recommended. When a Hyperion eyepiece is used with a 2" diagonal or prism, this Stop Ring can be employed to keep the internal elements of the 1.25" eyepiece from being damaged, especially in the case that additional finetuning rings are extending the original eyepiece body.
