Alstar Stereo Bino Viewer - Bundle with - 2" 4-Element 2X Barlow Lens

The Alstar Stereo Bino Viewer allows you to adapt two eyepieces to your telescope and view with both eyes simultaneously. In addition to eliminating eye fatigue associated with viewing through one eye for a prolonged period of time, this bino viewer also provides a three dimensional effect while observing many celestial objects.The Stereo Binocular Viewer will also improve contrast on deep sky objects as well as solar system objects. The Stereo Binocular Viewer is designed to work with Schmidt-Cassegrain telescopes (SCT) and many refracting telescopes.Features high quality FMC BAK-4 prisms reduce light loss. Each unit is quality control inspected for collimation and performance.The Stereo Binocular Viewer requires you use two eyepieces of equal focal lengths and optical design.

• Nearly 3D Viewing: The Binocular Viewer turns the telescope into a binocular; This replaces the fatigue of observing with one eye; This means you can easily provide an immersive 3D viewing experience for lunar and planetary observations
• With 1.85x and 3x Barlow: The BinoViewer will work on any telescope with approximately 4 inch of inward focus travel; If your telescope has less focus travel; you can adjust the focus using the 1.85x and 3x magnifying glass included with the BinoViewer
• With Two Eyepieces: The binocular is equipped with two 32mm plossl eyepieces; the internal brass ring will be firmly fixed without damaging the eyepieces; You will need two identical eyepieces of the same focal length to be able to use a bino-viewer
• Zoom In Twice As Much: Without the barlow lens; the planets would appear so small that hardly any detail would be visible; This 2X Barlow Lens doubles the magnification of the telescope's eyepiece without any significant reduction in optical quality
• Fully Multi-Coating: This Barlow lens utilizes a four-lens design with multiple layers of coating to magnify magnification without reducing contrast; This means that your power-boosted observations will be optimized for sharpness; clarity and brightness
