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 21mm eyepiece is as follows:With 14mm FTR: 17.6mmWith 28mm FTR: 15.5mmCombined FTR: 14mm2" Baader filter: 18.5mmRemoving first group of lenses: 32.2mmThe 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: Five Stars - perfect thankyou
Review: Oculare Baader Hyperion 21mm - Baader - Lente oculare Hyperion da 21 mm Provato su Celestron Regal m2 100 ED e Su vecchio rifrattore 120x1500. Risultati di nitidezza notevole, leggerissimi artefatti al bordo, grande luminosità e praticamente assenza di "fantasmi". Un oculare al vertice nella sua fascia di prezzo, e anche oltre. Un oculare versatile, a cui può essere diminuita la focale mediante l'inserzione di "anelli di regolazione", o aumentata (ma non per spotting scope) mediante l'asportazione del primo gruppo di lenti. Consente il montaggio di una coppia di polarizzatori da 2" manovrabili dall'esterno e naturalmente di filtri da 1,25". Costruzione robusta e ben curata, ma non a tenuta di gas. Ottimo il prezzo se paragonato.

### ⭐⭐⭐⭐ Kontrastreich, farbrein, scharf, passt NICHT auf Zeiss Spektiv.
*by P***T on 23 June 2015*

Vorher hatte ich ein Vixen LVW 22 auf meinem Zeiss Spektiv und das war fotografisch scharf bis an den Bildrand. Allerdings störte mich die grünliche Farbtönung und im Gegenlicht gab es Reflexe, die den Kontrast stark minderten. Deshalb erwarb ich das Hyperion 21mm. Das Okular ist voll tauglich für Tageslichtfotografie, sichtbare Reflexe gibt es keine, Farbe und Kontrast sind sehr gut. Die Zentrumsschärfe ist sehr gut, allerdings ist es nicht ganz bis zum Rand scharf, bzw. die Fokusebene ist nicht plan, sondern gewölbt. Dennoch liefert es mir bessere Fotos als das Vixen LVW22 und deshalb setze ich es auch weiterhin ein. Am Zeiss Astroadapter ist es verwendbar, es lässt sich allerdings nicht auf Unendlich fokussieren. Die Steckhülse ist nicht 24mm lang, sondern fast 27mm, deshalb gibt es auch mit dem Astroadapter von Baader Probleme. Deshalb habe ich die Steckhülse auf 26mm gekürzt, eine 2mm dicke Distanzscheibe zwischen den Adapter und das Okular gelegt, und habe an dem Adapter von Baader vorne den nach innen gebördelten Rand abgefeilt. Dann braucht man noch einen 3mm dicken O Ring. Erst dann passt das Okular auf das Spektiv, so daß Unendlichfokussierung möglich ist, daß es dicht ist und nichts wackelt. Es hat sich dann noch gezeigt, daß die Klemmung in dem Adapter sich löst, wenn man einige Stunden mit dem Spektiv in der Natur wandert. Deshalb habe ich noch den Spannring im Adapter entfernt und 3 zusätzliche Löcher gebohrt und Gewinde reingeschnitten und erst jetzt hält alles sicher und funktioniert.
