TS Optics 40 mm Plössl eyepiece with 1.25\" barrel. A good Plössl eyepiece outperforms a simple Kellner. Thanks to bulk purchasing, we can offer this type of eyepiece at a price for which one would only get simpler eyepieces elsewhere. However, the features are truly remarkable. The 40 mm Plössl offers the maximum field of view for a 1.25\" eyepiece and is an excellent wide-field eyepiece. With its long focal length of 40 mm, it is particularly suitable for slow telescopes like Cassegrains or refractors with a focal ratio of no faster than f\/8. The image remains bright, making the eyepiece suitable for observing nebulae, open star clusters, and galaxies, as well as for centering objects. Fields of application for Plössl eyepieces: Thanks to its four-element design, the Plössl is a true \"all-rounder.\" It does not introduce additional chromatic aberration into the system, unlike simpler eyepieces with fewer elements. As a result, these eyepieces can be used very well for lunar and planetary observation at higher magnifications. At lower magnifications, Plössl eyepieces are suitable for observing nebulae, star clusters, and galaxies, as they impress with a relatively distortion-free field of view. Astrophotographers can also work well with Plössl eyepieces, as they are suitable for eyepiece projection. The MgF2 coating prevents annoying reflections and provides good contrast. However, many projection adapters are too narrow for 32 mm or 40 mm focal length Plössl eyepieces.\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:20px;margin-top:30px;\"\u003eMain features\u003c\/h2\u003e\n\n\u003cp\u003eTS Optics quality for a reliable and satisfying observation experience.\u003c\/p\u003e\n\n\u003cul style=\"padding-left:20px;\"\u003e\n\n\u003cli\u003eFocal length (mm): 40\u003c\/li\u003e\n\n\u003cli\u003eField of view: 50°\u003c\/li\u003e\n\n\u003cli\u003eBarrel \/ thread: 1.25\"\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\u003ch2 style=\"font-size:20px;margin-top:30px;\"\u003eMain technical specifications\u003c\/h2\u003e\n\n\u003ctable style=\"width:100%;border-collapse:collapse;margin-top:10px;\"\u003e\u003ctbody\u003e\n\n\u003ctr\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003eBrand\u003c\/td\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003eTS Optics\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003eModel\u003c\/td\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003eTS-Optics 1.25\" Plössl Eyepiece - 40 mm focal length, 46° apparent field of view\"\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003eType\u003c\/td\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003eEyepieces\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003eFocal length (mm)\u003c\/td\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003e40\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003eField of view\u003c\/td\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003e50°\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003eBarrel \/ thread\u003c\/td\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003e1.25\"\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/tbody\u003e\u003c\/table\u003e\n\n\u003cdiv style=\"background-color:#f0f8ff;padding:15px;margin-top:30px;border-left:4px solid #007acc;\"\u003e\n\n\u003cstrong\u003eFree shipping\u003c\/strong\u003e\u003cbr\u003eTake advantage of free shipping throughout Italy for orders over €199.99!\u003c\/div\u003e\n\n\n\u003c\/div\u003e","brand":"TS Optics","offers":[{"title":"Default Title","offer_id":51120855515352,"sku":"TSP40","price":10.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/0722\/6072\/files\/ddd772f0dda68e0c1508c1f5b22812df.jpg?v=1764072878","url":"https:\/\/www.giordanoastronomia.it\/en\/products\/ts-optics-1-25-plossl-eyepiece-40-mm-di-lunghezza-focale-46-di-campo-visivo-apparente","provider":"Giordano Astronomia","version":"1.0","type":"link"}
