Product Description
Orion GiantView BT-100 Binocular Telescope
The Orion GiantView BT-100 Binocular Telescope is an excellent stargazing instrument, capable of viewing things from moon craters to nebulae. The fully multi-coated 100mm lenses gather over 56% more light than large 80mm astro binoculars. During the day, these binoculars can function as a spotting scope for long range terrestrial observation as well.
The GiantView BT-100 Binocular Telescope can be setup and the deck for long distance views. The 45° angle eyepiece holders make observing very comfortable.
The binoculars come with an included pair of 18mm 65° flat field 1.25" eyepieces for 31x magnification and 2.13° field of view, but the user can also switch and use their own 1.25" eyepieces as well.
