Product Details
Another novel way to change eyepiece focal length is to use a Baader 2" Filter in between the Hyperion negative element and main body, just like a small Fine Tuning Ring. The 8.5mm thickness of the filter cell will have a similar (milder) effect in reducing the Hyperion's focal length. This also allows the use of 2" filters with Hyperions, something that is not possible with any other 1.25" eyepiece.
Customer Note: Removal and installation of the front negative element should be done in a clean environment to prevent dust or other contamination from depositing on the internal elements (which are very difficult to clean). Also, please be aware that the Baader 24mm Hyperion Eyepiece is not able to make use of the Fine Tuning Rings, due to the difference in its optical design.
