This type of aberration occurs when a lens fails to focus all colors to the same convergence point, resulting in color fringing around bright objects. Lanthanum glass reduces this effect, leading to clearer and sharper images.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eImproved Sharpness and Contrast\u003c\/strong\u003e: Eyepieces with Lanthanum glass typically provide sharper images with better contrast. This is crucial when observing celestial objects, as it allows for more detailed and vivid views, whether you're looking at the Moon's craters, Jupiter's bands, or the rings of Saturn.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eEnhanced Color Correction\u003c\/strong\u003e: The unique properties of Lanthanum glass help in better color correction across the visible spectrum. This means that the views through such eyepieces are more true to life and free from color distortions, making them ideal for both planetary and deep-sky observations.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eLong Eye Relief\u003c\/strong\u003e: Eyepieces with Lanthanum glass often offer long eye relief, making them comfortable for extended use, especially for observers who wear glasses. Eye relief is the distance from the last surface of an eyepiece at which the eye can obtain the full viewing angle. Longer eye relief provides a more comfortable viewing experience.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eHigh Refractive Index\u003c\/strong\u003e: Lanthanum glass has a high refractive index, which allows for the design of eyepieces with fewer elements. Fewer elements can mean lighter eyepieces and less internal light loss, leading to brighter images.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eDurability and Quality\u003c\/strong\u003e: Lanthanum glass is durable and maintains its optical properties over time, ensuring that the eyepiece remains a valuable part of your astronomy kit for years.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003c\/div\u003e\n\u003ch3 style=\"text-align: center;\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eLong Perng 8-20mm 2.5X Zoom Lanthanum Eyepiece Specifications\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ch4\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eFocal Length:  8 mm - 20 mm\u003c\/span\u003e\u003c\/h4\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch4\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eOptical Design:  7 elements in 5 groups\u003c\/span\u003e\u003c\/h4\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch4\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eLens Material:  Lanthanum\u003c\/span\u003e\u003c\/h4\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch4\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eEye Relief:  20 mm at lowest power\u003c\/span\u003e\u003c\/h4\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch4\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eField of View:  40 - 60 degrees\u003c\/span\u003e\u003c\/h4\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch4\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eOptical Coating:  FMC, or Fully Multi Coated\u003c\/span\u003e\u003c\/h4\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch4\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eBody Material:  Aluminum alloy\u003c\/span\u003e\u003c\/h4\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch4\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eBarrel Size:  1.25\"\u003c\/span\u003e\u003c\/h4\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch4\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eEye Cup Design:  Twist up\u003c\/span\u003e\u003c\/h4\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch4\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eMade in Taiwan\u003c\/span\u003e\u003c\/h4\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Long Perng","offers":[{"title":"Default Title","offer_id":40479414321265,"sku":"LON-E0820Z-UA","price":198.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/files\/LP_Eyepiece.jpg?v=1776459165","url":"https:\/\/khanscope.com\/fr-fr\/products\/long-perng-8mm-20mm-zoom-1-25-eyepiece-e0820z-ua","provider":"Khan Scope Centre","version":"1.0","type":"link"}
