By filtering out many polarized lights in diffuse reflection, the intensity of light in the sky is reduced, darkening the sky and increasing the contrast between blue sky and white clouds. When taking actual shots, you need to look at the viewfinder and rotate the front mirror. The effect is most pronounced when the sky is darkest in the viewfinder, with a difference of 90 degrees between the darkest and brightest. You can switch to any angle between the darkest and brightest as needed.\u003cbr\u003e- Polarizers are lenses manufactured based on the principle of polarization of light, which can eliminate and filter out scattered light in a beam, prevent ultraviolet rays, and filter polarized light. A good polarizer can achieve color distortion in the surrounding environment, clear edges of objects, effective recognition of different colored signal lights, and reduce the amount of ultraviolet radiation entering the pupil.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eSpecification:\u003c\/b\u003e\u003cbr\u003e- Product name: adjustable astronomical polarizer\u003cbr\u003e- Size: 1.25-inch\/31.7mm\u003cbr\u003e- Material: high quality metal, optical glass lenses\u003cbr\u003e- Function: By rotating the adjustment ring, the transparency can be adjusted from 1% to 40%, reducing the brightness of the moon or planet for clear observation.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eUsing Methods:\u003c\/b\u003e\u003cbr\u003e- Method 1: Connect the eyepiece for use.\u003cbr\u003e- Method 2: Separate two filters, one connected to the eyepiece and one connected to the zenith mirror or Barlow. Rotate the eyepiece to change the transparency.\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Included:\u003c\/b\u003e\u003cbr\u003e- 1 x Polarizing Filter\u003c\/p\u003e","brand":"Thanksbuyer Online,SDR Radio, Testers and Measurement devices, Astronomy products, Audio Amplifer and Decoders","offers":[{"title":"Default Title","offer_id":41029116231729,"sku":"102291","price":15.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0578\/4790\/6353\/files\/1779673665-1.jpg?v=1780391289","url":"https:\/\/www.thanksbuyer.com\/products\/angeleyes-1-25-inch-31-7mm-adjustable-polarizing-filter-telescope-variable-polarizer-for-eyepiece-zenith-mirror","provider":"Thanksbuyer Online,SDR Radio, Testers and Measurement devices, Astronomy products,  Audio Amplifer and Decoders","version":"1.0","type":"link"}
