|Baader 17mm Hyperion Eyepiece|
| 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! |
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 effective FL of the 17mm eyepiece is as follows:
With 14mm FTR: 13.1mm
With 28mm FTR: 10.8mm
Combined FTR: 9.2mm
2" Baader filter: 14.6mm
Removing first group of lenses: 21.8mm
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. The Hyperions work as well for photographic applications as they do for visual use.
