Transform your stargazing experience with the Explore Scientific 2" Variable Polarizing Filter, engineered for precision and comfort in every aspect of celestial observation. This filter allows for precise light transmission control, ranging from 40% to a remarkably dim 1%, giving you the freedom to view bright objects, like the Moon and Sun (with an appropriate solar protection filter), without blinding glare or washed-out details. With its easy-to-use rotating mechanism, you can instantly adjust the brightness by simply twisting the two halves of the filter, tailoring the light to your exact preference and eliminating the need for multiple filters.

This filter’s construction from highly parallel optical glass is a game-changer. Unlike lower-grade filters, which often degrade image quality or introduce unwanted color shifts, this glass maintains the natural, true-to-life colors and fine details of every celestial object. The filter's neutral gray tone preserves the authentic hues of planets, stars, and the Moon’s craters, making it ideal for observing color-sensitive features like the Great Red Spot on Jupiter or the subtle color variations on Mars. This is especially important when conducting precise observation or capturing images, where accurate color representation matters.

Built with astronomy professionals and serious hobbyists in mind, the black anodized aluminum housing is both durable and lightweight, designed to withstand frequent handling and changes between telescope setups. Its universal 2" threading allows it to fit securely on virtually any telescope with a 2" eyepiece, and it’s compatible with other color filters, offering a high degree of customization. Stack it with color or specialty filters to fine-tune contrast and hue, creating a perfect setup tailored to specific planets, nebulae, or other deep-sky objects.

This filter is especially valuable when paired with a Herschel wedge or used on large-aperture telescopes, where managing brightness is essential. With its finely tunable light control, it reduces brightness to safe, comfortable levels, allowing you to observe in incredible detail without eye strain. The filter includes a dust cover to protect the optics from scratches and dust, preserving clarity and ensuring that the glass remains pristine for the next use.

Every detail of this filter is designed to make your observation experience safer, clearer, and more immersive. If you’re ready to move beyond basic filters and embrace a tool that provides expert-level control and visual fidelity, the Explore Scientific 2" Variable Polarizing Filter is your solution. It’s more than just a filter—it’s the key to seeing the cosmos as vividly as possible, with precision, clarity, and complete control at your fingertips.
