## Description

Modular dual 31.7mm/50.8mm 68 degree widefield eyepieces that performs as well as eyepieces three times its price. 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: 13.1mmWith 28mm FTR: 10.8mmCombined FTR: 9.2mm2" Baader filter: 14.6mmRemoving first group of lenses: 21.8mmThe 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.

Review: Love it so far - This is a huge step up from the basic ploski lenses that you get with a telescope. It provides more than enough relief for me to be able to keep my glasses on while still seeing objects clearly. I did not notice distortion near the edges of the field. I did not like pairing it with a Barlow lens because the eye relief was almost as bad as the ploski lenses again. Also be aware that it is huge, and considerably heavier than the ploski lenses that come with your telescope.
Review: Impresionante Ocular. - Es un ocular caro, pero que en otros comercios ronda los 125 euros. Viene en una fundita de cuero y dos funditas de goma como proteccion del ocular, con la opción de poder utilizarse en telescopios de 1,25"pulgadas, o si se le desenrosca la ultima parte se puede utilizar con telescopios de oculares de 2". Su calidad es excelente, ademas con un buen angulo de vision. Existe la posibilidad de comprar un adaptador de rosca, que con una anilla tipo T2 te permite enroscarlo a una camara reflex para tomar fotografias (ninguno de los dos se vende en desertcart).

### ⭐⭐⭐⭐⭐ Contento
*by L***B on 29 December 2012*

Por poco margen, pero el mejor precio del mercado. Objetivo versátil y de calidad. Lástima que sólo haya alguna unidad, sólo de alguna determinada longitud focal, y de forma intermitente. Muy recomendable si tienes el dilema de qué diámetro ocular elegir, ya que este lleva los dos. La calidad, para mí muy buena, pero no lo he podido comparar con Paragones y cosas así (que valen tres o cuatro veces más). Lo empleo en un Cassegrain de 5 1/2" (para planetaria) y en un Dob de 12 " (para cielo profundo). Recomendable.
