SVBONY SV139 Telescope Filter Bundle with Barlow Lens and Phone Adapter

The SV139 1.25" ND8 Neutral Density Filter is designed to enhance your telescope viewing experience by reducing the overall brightness of the Moon's surface. This premium-quality filter is crafted with an aluminum frame, metal thread, and optical glass, ensuring both durability and exceptional optical performance.

With an optical density value of 0.9, the ND8 filter transmits only 12.5% of the incoming light, allowing you to observe the Moon's finer details and surface features without the glare. The filter's multi-layer coating guarantees high-quality optics, delivering outstanding image sharpness and perfect color neutrality.

Versatile in its applications, this neutral density filter can be used with a variety of optical devices, including telescopes, binoculars, monoculars, spotting scopes, and even microscopes. Its standard M28.5x0.6mm thread allows for easy integration with compatible eyepieces, providing a seamless and customizable viewing experience.

Complementing the filter is the included 2x Barlow lens, which doubles the magnification of any 1.25-inch eyepiece. This accessory effectively increases the capability of your existing eyepiece set, offering enhanced magnification without compromising the wide field of view or visual comfort.

Crafted from premium aluminum stock and featuring a sleek black anodized body, the SV139 filter and Barlow lens combination is built to last. The sturdy construction and precise machining ensure long-term durability, making this setup a reliable companion for your astronomical observations.

In addition to the filter and Barlow lens, the package includes a Universal Cell Phone Adapter Mount. This versatile mount supports eyepiece diameters ranging from 25mm to 48mm, allowing you to capture stunning lunar and planetary images using your smartphone. The soft contact surfaces protect your device from scratches and damage, while the adjustable clamping force ensures a secure and stable connection.

The SV139 filter is particularly useful during the last quarter and first quarter moon phases, when the illuminated portion of the lunar surface is approximately half. By reducing the overall brightness, the filter enables you to observe and capture more detailed features on the Moon's surface, enhancing your viewing experience.

With its high-quality construction, exceptional optical performance, and versatile compatibility, the SV139 1.25" ND8 Neutral Density Filter, 2x Barlow Lens, and Universal Cell Phone Adapter Mount are the perfect companions for your telescope-based astronomical explorations and astrophotography endeavors.
