The OVNI Night Vision range consists of 2 « Night Vision Eyepieces » mainly intended for astronomers practicing visual observation.
★ OVNI-M is a monocular with 26mm focal length and 1.25" barrel. It fits into the eyepiece holder of a reflector or refractor telescope and you can observe through the glass part of the eyepiece. It can be associated with a focal reducer, a barlow, filters...
★ OVNI-B is a binoviewer with 1.25" and 2" barrels. It fits into the eyepiece holder of a reflector or refractor telescope and integrates 2 eyepieces with a focal length of 27mm. It can also be associated with a focal reducer, a barlow, filters...
Note that they both have manual gain control features to reduce or eliminate scintillation (may be visible when using a filter).
OVNI-M and OVNI-B can be used in 3 ways: :
at the focal point, by inserting them directly into the eyepiece holder of a reflector or refractor telescope
in afocal, by using them on a traditional eyepiece. This makes it possible to increase or decrease the magnification and the field of observation.
- hand-held (like binoculars) for very low magnification and wide field observations. It is possible to observe large structures such as the Barnard Loop, the California Nebula, M8, M20...
OVNI-M and OVNI-B have been developed for astronomy and are optimized to be compatible with all refractor and reflector telescopes (from the smallest to the largest). They benefit from the diopter adjustment to be adapted to the sight of all astronomers. Many accessories are also available (included or optional).
