Omegon Oberon 19mm 82° 2″ Eyepiece
Look through the Oberon 19mm and you will simply forget about the edges of the field of view. This wide-angle eyepiece with an 82-degree field of view creates the impression that you are looking directly into space - with no frame at all. The 19mm focal length combined with a 2-inch barrel makes it an excellent choice for sweeping, panoramic views of large objects such as nebulae, open clusters and the Milky Way.
Rugged build for real observing conditions
The eyepiece body is machined from anodised aluminium with a matt black finish that suppresses internal reflections. A rubber grip ensures a secure hold even on cold nights. The fold-down eye cup adjusts easily to suit observers both with and without glasses. The optics feature fully multi-coated surfaces for maximum light transmission.
Waterproof and nitrogen-filled
The Oberon 19mm is waterproof and filled with inert nitrogen gas, so the internal optics will not fog up even when temperature or humidity changes suddenly. This is a real practical advantage during night sessions in the field, where temperatures can drop quickly. A nitrogen-filled waterproof eyepiece simply withstands conditions that would damage ordinary eyepieces. The barrel also includes an internal filter thread, so you can easily attach a Moon filter or a light pollution filter.
