Baader Hyperion Eyepieces
Modular dual 31.7mm/50.8mm 68 degree widefield eyepieces that performs as well as eyepieces three times its price.
Baader Hyperion Eyepieces Main Features:
- Hyperion 68° eyepieces are multifunctional.
- Here are the most important features:
- 1.25" and 2" barrels with self-locking safety groove
- Unscrewing the 1.25" barrel (which contains the first group of lenses) allows changing focal length by adding our finetuning rings.
- The M48 thread located between the 1.25" and 2" barrels allows inserting a 2" filter.
All eyepieces are suitable for afocal and classical eyepiece projection.
The Hyperion design has has both a 31.7mm (1 1/4") and 50.8mm (2") barrel for fitting into either size focuser or diagonal. Both barrel sizes have a safety groove for safe use in your telescope. Each Hyperion features Baader's PHANTOM-GROUP Multi-Coatings for maximum light transmission and the ultimate in image contrast. There are two photographic threads on each Hyperion, M43 and SP54. These threads are located under the rubber eye-cap, or rather beneath the thread protecting ring which is made of high-quality and aging-resistant silicone rubber.
A variety of focal lengths can be obtained from each Hyperion. A second focal length is easily acheived by removing the first group of lenses. Additional FL can then be acheived by purchasing a 14mm Fine Tuning Ring (FTR), 28mm FTR, combining the 14mm and 28mm FTR, and with 2" Baader Filter (height 8mm).
The Hyperion can be combined with a Baader adaptor ring to mount a camera directly onto the eyepiece. In addition, there are a large number of Baader adapting rings and fittings to make the Hyperion suitable for (almost) every task in astronomical - and nature - photography as a high quality projection optic or as a tele-extender.
Each Hyperion is supplied with a soft leather storage bag for safe keeping, and two dust caps for storing the eyepiece with either the rubber eyeguard either folded up or down!
