I am selling my set of Hyperion Eyepieces as they are not getting enough use to justify keeping them.
The set comprises:
21mm
17mm Sale pending
13mm
8mm
3.5mm
I don’t have any of the original boxes.
They are all in good used condition.
* Eye Relief: 20mm
* Apparent field of view: 68 degrees (61 degrees w/21mm Hyperion)
* Weight: Between 11.6-14.7 ounces (328-417 grams)
* Coatings: Fully broadband multi-coated
The Hyperions all have very large eye lenses and long eye relief. This makes them ideal for those who have astigmatism and must wear eyeglasses. The Hyperions also come with Baader’s Phantom Group multi-coatings for minimal light loss and scattering.
The Hyperions’ eyecups are removable, exposing M43 threads.
The Hyperions are relatively inexpensive wide-fields, and due to their low prices and the design requirement of large eye lenses and long eye relief which limits other aspects of the optical design, they are really meant for slower f/ratio telescopes. They will do great at f/15 or f/10, and okay down to f/6.
$600 for the set or $145 each
