The Baader Hyperion 28mm Finetuning-Ring will allow you to easily change the focal length of your Hyperion eyepiece. The finetuning-ring has an outside diameter of 2” and is equipped with a male M48 thread on one end and a female M48 thread on the other. The ring simply attaches to the ring between the front negative element and the main body of the Hyperion eyepiece (not included) and this additional spacing decreases the focal length and increases the magnification. Please note that the finetuning ring is not compatible with the Baader 24mm Hyperion Eyepiece, due to a difference in optical specification.
Baader Hyperion Finetuning-Ring 28mm
- Using one (or two) fine-tuning rings with one Hyperion eyepiece and you get the function of two/four eyepieces.
- The Baader 28mm Hyperion Fine Tuning Ring is made to match the Hyperion finish, and are fully internally sharp v-threaded and blackened to eliminate stray light reflections from the internal surfaces
Please note that Baader 24mm Hyperion Eyepiece will not accept the Fine-tuning Rings due to a difference in optical design.
