The Barium eyepieces can be used in 1.25\" focusers. They\'re reversed Kellner eyepieces where one of the lenses contain Barium. As a result the image quality is definitely better than the one of Kellner eyepieces and the eyepiece provides a wider field. Recommended for slow telescopes (F/8 and under) but perform well even in faster scopes. Ideal for outreach events. The eyepieces contain standard filter thread and the eye rubber protects from stray light. Recommended for medium magnifications.

Review from a customer (Imre Lorincz): these eyepieces provide excellent light transmission (I guess because of the 3 elements). For example the 20mm Barium has a light transmission similar to a 21mm Pentax XL, whose light transmission is 95%...

Another review (Istvan Csuti): the image brightness was evident at first sight. I couldn\'t detect any reflection even with the brighter objects.

Pros

Egy házi készítésű távcsőbe lett beszerelve, nem a világ legjobb minőségű okulárja, de a várakozásaimnak megfelelően javította fel az alkotott kép minőségét.
