1. The standard eyecup is the large height-adjustable eyecup that
also fastens onto the M43 photo-thread of the eyepiece. By ro-
tating it counterclockwise, the height will increase. This eyecup
easily unthreads by simply rotating it upwards further than the
uppermost stop – this reveals the M43-thread connection. This
eyecup is preinstalled when the eyepiece is shipped and the
most common eyecup for use with a telescope
2. A folding rubber eyecup alternatively fits straight onto the
M43-thread. This is the preferred solution for observers with-
out glasses at a binoviewer. It gives you enough room for your
nose, at the same time it provides good support to keep the
perfect eye distance.
3. An even lower eyecup with foldable winged eye shield especially
serves for wearers of eye glasses. The flappable side shields
block stray light and side image information not part of the eye-
piece field of view. This helps to concentrate on the target when
using a binoviewer.
In case of need an optional, 7.5 mm long extension tube with M43-
threads
(# 2954250)
is available for further finetuning the position
of the eyecups. This extension tube has one male and one female
M43-thread.
Three eyecups are shipped together with the
eyepiece. The M43 photo/video-thread is
located on the top of the eyepiece.
