BINOVIEWERS

Product description:

Next generation bino-viewers - focus on any telescope without extending the focal length

A clear image for both eyes, with any telescope. Without any tricks or optical lenses. Omegon Pro bino-viewers make this possible. A new optical system makes it easy to focus - even with Newtonian telescopes and short refractors - and without changing the focal length or magnification. With absolutely no need of an optical path corrector or Barlow lens, but with a fantastically good image!

The advantages in a nutshell

bino-viewers with a beam splitter mirror - better contrast and less optical errors. The result - a much better image
zero back focus - you can achieve focus with any telescope
no path corrector or Barlow lens necessary
even small magnifications with a wide field of view are possible, as the focal length is not extended
Twist Lock System - your eyepieces are centred automatically and clamped flat

A bino-viewer for every telescope - zero back-focus
Normally, every standard bino-viewers need a huge 100mm optical path, and that means not every telescope is suitable for it. Or you need a corrector with a long extender, which also extends the focal length. Not anymore! Use these bino-viewers on your Newtonian telescope or on any other telescope. Just slide in, focus and observe. Now you can enjoy the night sky with both eyes - through any telescope.
For the Moon, Planets and deep sky objects
Use your favourite eyepieces in your new bino-viewers. Whether short, medium or long focal length - the magnification always corresponds to the respective eyepiece and remains unchanged. Even the field of view stays the same, as if you were observing in a normal way through your eyepiece using just one eye. The extra plus - you can now not just use high magnifications for planets, but also lower magnifications for extended deep-sky objects. Try that using ordinary bino-viewers!
Beam splitter mirror - the concept for a better image
These bino-viewers are really out of the ordinary! The completely different system employs a 99% reflection beam splitter mirror and no prism. What are the advantages? - This optical system provides you with

Omegon-Pro-Tritron-bino-viewers-1-25-2

A better image
More contrast
Less image aberrations

Thanks to the mirror system, less light is lost meaning you get a bright image - even at higher magnifications.

Sliding System - perfect viewing for everyone

These bino-viewers work quite differently - Omegon bino-viewers use a modern sliding system with no hinged bridge. The scale supplied lets you precisely set your own personal interpupillary distance to between 58 and 74mm - allowing the whole family to observe through these bino-viewers, with even small children able to marvel at the Moon and planets.

1.25" Twist Lock system - centres eyepieces firmly and gently

This feature shows the high-quality design of Omegon bino-viewers - the Twist Lock 1.25" adapter automatically centres your eyepieces and firmly and gently clamps them in place over a large 15mm area. Gone are the days when your eyepieces have deep notches from clamping screws drilled into their barrels, The Twist Lock system ensures a long life for your eyepieces and maximum enjoyment of your accessories.

Upright image

The seven lens element system provides you with an upright image. With Newtonian telescopes completely without need of any additional optical components. For refractors and SC telescopes, we recommend using them in combination with the optional penta-prism for an upright image.

Omegon Binocular head Binoviewer 1.25'' #33077

Manufacturer's product description:

Relaxed, almost 3D viewing: Ideal for planetary and lunar observing

A bino-viewer turns your telescope into binoculars. Instead of the usual (and rather unnatural) way of observing using only one eye, you can observe in a totally relaxed way instead of having to squint. This not only means that you will not tire as quickly, but also that you will experience a 3D effect in your lunar and planetary observing. And also, the image will appear brighter and larger on physiological grounds. Even experienced observers will discover new details on the Moon!

The image orientation is not changed by the bino-viewer. So if you, for example, use an Amici prism to obtain an upright and non-reversed lunar or planetary image, then this orientation will remain the same through the bino-viewer.

You will need two identical eyepieces of the same focal length to be able to use a bino-viewer. Each eyepiece can also be separately focused on the bino-viewer.

Our expert comment:

A bino-viewer has the advantage of being able to observe with both eyes. However, these instruments are mainly designed for observing brighter objects such as planets, the Moon and bright deep-sky objects.

Very faint objects should still be observed using just one eye. But bright objects do appear particularly fascinating in bino-viewers.

Omegon path corrector for 1.25'', 1.6X bino-viewers #44201

Product description:

Glass path corrector for bino-viewer attachment CURRENTLY NOT AVAILABLE

Bino-viewers need a certain optical path length. With many telescopes, such as Newtonians and fast refractors, there is insufficient focuser travel for them. The focuser hits the inner stop before the object comes into focus.

Glass path correctors solve this problem

A combination of lenses moves the focal plane further out, thus enabling almost the entire optical pathway required by the bino-viewers. Straight-view bino-viewers, such as the Baader wide-field bino-viewers, the BW bino-viewers, the TS bino-viewers, etc. can be used on any telescope. The lengthening factor is approximately 2.3 times.

Our expert comment:

This lens can be screwed into the filter thread of 1.25 inch eyepieces as a Barlow. It extends by a factor of 1.6. A similar model is sold under the brand name 'Paralux 1.6X Barlow lens'.
