The TeleVue Bino Vue:
This attachment allows you to use both eyes for observation, greatly enhancing the visual impression. With this binocular, you can see the moon, planets and deep sky objects with an impressive 3D effect. It fits any type of telescope by optically eliminating the 130 mm light path. A special lens ensures that the binocular is parfocal, so you don't have to refocus when changing eyepieces. All in all, the TeleVue binocular is one of the best eyepieces currently available on the market.
Our expert comment:
The version with focal length doubler is ideal for Newtonian telescopes and fast refractors up to f/6.
If you have an SC or Maksutov with primary mirror focussing, you do not need the
focal length doubler and can use TeleVue Binocular head Bino Vue Body.
