The compensator lens also corrects for prism effects that can degrade high power viewing. Even larger instruments will find the Bino Vue extremely versatile. SCTs have enough focus travel to use Bino Vue without the compensator. Finally, Tele Vue tests the collimation and image quality of each unit. This time and labor intesive operation is essential for a binocular viewer used at planetary magnifications.
Collimation is critical and delicate.
Vue should it be required. You always have that assurance with Tele Vue. If you use Bino Vue with any of our telescopes for terrestrial viewing, you will enter a new world of visual experience. Indeed until you go to very high powers, you may prefer these views with seemingly darker sky backgrounds. Copyright 1996 Tele Vue Optics.
