TS Optics Binoviewer - for comfortably using your telescope with both eyesFor 1 1/4" eyepieces - can be used on most telescopes with 1 1/4" adaption -
Binocular viewing is widely considered much more comfortable than viewing with one eye. This is especially true during longer observing sessions. Usually the eyes will quickly tire and you will no longer see as much detail as the telescope would be able to show you. Often, especially on the moon and planets, you will see more detail and with much more observing comfort than with single eye observing.Advantages of Binocular Observing
Binocular observing of nebulae and star clusters
- relaxed observing for long periods without straining or tiring your eyes
- enhanced visibility of details
- Seeing is better compensated
- many users also report a perceived three-dimensional effect that makes objects look more natural
The most common use of binoviewers is for observing the moon and the planets. One of the reason for this is that on some telescopes it is difficult to achieve a low magnification, so some objects will not fit into the field of view. But there is also the opinion by some people that a binoviewer is split 50/50 for both eyes. The theory may be sound, but we nonetheless do not agree: You will be surprised how much you can see on deep sky objects through a binoviewer! The sky´s background will get darker and the brain works wonders in overlaying the two images in your mind in order to procedure a brighter than expected impression even of faint objects! Add to that the additional comfort of observing with both eyes and the perceived three-dimensional effect and you will see that binoviewers are indeed ideal also for deep sky observing!Can be used with almost all telescopes?
Essentially the binoviewer can be used on any telescope which accepts 1 1/4" eyepieces. However it does consume about 100 mm optical length, meaning that in many telescopes you will need to use a glass path corrector in order to reach a focused image.
In straight through vision the binoviewer can be focused in most refractors that work with a 2" star diagonal.
Many Maksutov-Cassegrains and virually all Schmidt-Cassegrains have sufficient focusing range so that you will usually not need a glass path corrector.
For all other telescopes we will offer the TS 1.6x glass path corrector. In combination with the TS binoviewer you will get a magnification of 2.5x with full compensation of the optical path. So you can use the binoviewer with all telescopes, including newtonians.Delivery contents
