You will see spectacular views of comets and star clusters

Make a great view even better with Vixen's BT81S-A Binocular Telescope. Compared with the previous model "BT80 - A", shortening the focal length shortened the total length by about 100 mm. Improve image quality by reviewing optical design. By changing the eyepiece part, the height is 40 mm lower, weight is about 900 g lighter, making it more compact.

 

  • No immediate observation at all angles

    With an eyepiece section with a 45 degree angle, you can enjoy the starry sky casually.

  • Combinations that can achieve high stability

    For the BT81S - A lens barrel, we recommend using a combination of HF2 / Ladder table which adopt free stop type and SXG - HAL130 tripod of high rigidity.

  • 8x magnification and 80mm objective lenses: The 8x magnification and 80mm objective lenses on the Vixen Astronomical Binoculars BT81S-A allow for a powerful viewing experience. The larger the objective lens, the more light it can gather, resulting in brighter and clearer images. The 8x magnification brings objects closer, making them easier to observe and study.
  • BAK-4 prisms for high image quality: The BAK-4 prisms used in these binoculars are made of a high-quality glass that is known for its clarity and light transmission. This results in sharp and detailed images, even in low light conditions.
  • Fully multi-coated optics for bright and clear images: The fully multi-coated optics on the BT81S-A binoculars means that all of the lenses have been coated with multiple layers of anti-reflective coatings. This improves the overall light transmission and reduces glare, resulting in even brighter and clearer images.
  • Wide field of view of 6.5 degrees: The wide field of view of 6.5 degrees on these binoculars allows for a large area of the sky to be observed at once. This is particularly useful for observing objects that are moving across the sky, such as comets and satellites.
  • Long eye relief of 18mm for comfortable viewing: The long eye relief of 18mm on the BT81S-A binoculars means that the user can comfortably view the image even when wearing glasses. This is achieved by positioning the eyepiece further away from the eye, and allows for a more relaxed viewing experience.
  • Waterproof and fog-proof design: The waterproof and fog-proof design of these binoculars means that they can be used in a variety of weather conditions without fear of damage. This makes them suitable for outdoor use, and they can be used in humid or damp conditions without fogging up.
  • Adjustable eyecups for comfortable use with or without glasses: The adjustable eyecups on the BT81S-A binoculars can be twisted up or down to accommodate the user's eyes. This allows for a more comfortable viewing experience and also helps to prevent stray light from entering the eyepiece, resulting in a clearer image.
  • Durable aluminum body: The binoculars are built with durable aluminum body, this ensures that the binoculars are robust and can withstand the rigors of regular use.
  • Comes with a carrying case and strap for easy transport: Finally, the Vixen Astronomical Binoculars BT81S-A comes with a carrying case and strap, making it easy to transport them to different observing locations.
