Baader Hyperion Aspheric 36 mm - 72° Wide Angle Eyepiece
Simple Erfle designs, offered for low money under different names, have significantly less off-axis performance. Light rays near the field stop are refracted stronger than rays near the principal axis. This results unsharp pictures near the rim, especially with uncorrected systems.

The aspherical correction corrects for these abberations. Image definition remains very good across the entire field and distortions are reduced to a minimum. And what is more, the eyepiece can be kept more compact and lightweight.

Connection of digital cameras:

The eyepiece comes with two support threads for adaptation of digital cameras: 1x M43 and 1x M54. Starting from these threads, there are many adaptation possibilities:
Adaption to T2 for SLR cameras
Adaption to the filter thread of most compact digital cameras

"Sehr gutes Preis-Leistungs-Verhältnis. Ich konnte das Okular leider bisher nur einmal ausprobieren, aber es hat an meinem Orion-Optics UK VX8 eine sehr gute Figur gemacht. Abbildungsfehler sind mir nicht aufgefallen."

"Mangels klarem Himmel bislang erst einmal im Einsatz aber das war schon Klasse! Dem ersten Eindruck nach definitiv keine schlechte Investition. Auf einen ausgiebigen Test freu ich mich schon."

"Very nice and professional looking 2"" eyepiece with sufficiently large field of view which doesn´t cost as an air-plane. When used with coma-corrector it offers pinpoint stars almost from corner to corner. The only caveat: when used in the broad daylight onto Skywatcher 1501P it shows noticeable shadow in the centre of image. It´s origin arises due to small pupil size during the daylight observation so the shadow from the secondary mirror shows itself in such a way. During the night this effect is non-existent."

"Gute Abbildung, angenehmer Augenabstand und Einblickwinkel"

"Super Weitwinkel-Okular mit sauberer Darstellung auch am Rand. Es liegt zwar ein 1 1/4´´ Adapter bei; mit diesem wird das Bild am Rand beschnitten - für das volle Potential sollte es also mit einem 2´´ Auszug verwendet werden. Wie auch die anderen Hyperion Okulare kann die Augenmuschel abgenommen werden und mit einem entsprechenden Adapter (nicht im Lieferumfang) an ein T2-Gewinde befestigt werden."

"Ich verwende das Okular an meinem APO 127/952 als Übersichtsokular. Verarbeitung und Optik finde ich Top. Sehr kompakt und leicht. Mit längeren Okularen hat man oft das Problem mit einem Amici-Prisma dass der Fokkusierweg ausgeht. Das ist bei diesem Okular nicht der Fall. Preis/Leistung Top!"
