⇩ OVNI-B (Binoviewer version) ⇩

OVNI-B is the only night vision binoviewer in the world designed for astronomy !!! Made in France, it integrates an « Astronomy Grade » intensifier tube which is one of the many OVNI Night Vision innovations (learn more). Its 27mm focal length eyepieces + 31,75mm/1.25" and 50,8mm/2" barrels allows it to be used with all telescopes. Weighing only 500g, it revolutionizes the observation of the sky by benefiting from the most recent technological advances designed in our workshop.

No more loss of light or backfocus problems, the OVNI-B frees itself from all the limitations of astronomy binoviewers. Not only is it possible to use it directly in prime focus (without barlow or OCA) of any telescope. But it is even possible to use it in afocal, i.e. on a traditional eyepiece acting as a focal reducer (see photo gallery below). This makes it possible to observe the deep sky at low magnification and very wide field. Conversely, it can be associated with a barlow to increase the magnification. Without forgetting to use it by hand (like a pair of binoculars), with the possibility of adding photo objectives. The OVNI-B has functions that are essential to astronomy such as autogated, manual gain control, a white phosphor tube (very natural colour) ...

We've specially engineered this binoviewer for astronomers who enjoy visual observation.

Features

★ Autogated to protect the tube in case of high light intensity.

★ Manual gain control to reduce or eliminate scintillation (mainly when using a filter).

★ Diopter adjustment to adapt to the sight of each user (myopic, astigmatic, spectacle wearers, everyone can observe).

★ Interpupillary distance (IPD) adjustment from 53mm to 72mm to fit each person's morphology.

★ Anti-reflective blackened inner edges and multi-coated lenses for maximum contrast (visible light & near infrared).

Included accessories

★ 27mm F/1.2 front lens that delivers high transmission from 390nm to 1000nm

★ 1.25" and 2" barrels with thread for filters

★ CS/C-mount adapter

★ 42mm adapter (M42)

★ safety lanyard

★ travel bag

★ 2 AA batteries

★ tube test report

★ flexible and 360° rotatable eyeguards

★ optional accessories are available (see accessories)

OVNI-B is available in 3 versions. The FOM is the main performance measure of an intensifier tube and each OVNI-B is delivered with a tube test report measuring FOM, SNR, EBI, Luminous Gain, Luminous Sensitivity, Resolution...

For USA users please note that OVNI-B is ITAR Free.

« Astronomy grade » intensifiers tubes is an innovation of OVNI Night Vision meaning that they are specially manufactured for astronomy by combining the best performance of GEN3 filmless/unfilmed tubes and the extended lifetime of GEN3 thinfilmed tubes.
