If you combine 2 individual refractors into one device, a bio-telescope is created. The resulting possibilities are fantastic: two-eyed observation of planets AND deep-sky objects with the highest resolution, color corection and contrast. APM offers you exclusive devices.
Make a great view even better with Vixen's BT81S-A Binocular Telescope. You will see spectacular views of comets and star clusters. The Magnesium Fluoride coated, air space doublet design, dramatically reduces chromatic aberration for magnificent views.
