You can easily and reliably verify when you have reached the correct focus point: no more mistakes!\u003cbr\u003e How to mount the mask on the telescope:\u003cbr\u003e TS Optics Bahtinov mask for telescopes from 150mm to 200mm in diameter\u003cbr\u003e Each mask comes with 2 plastic screws used to securely rest it on your telescope. Simply mount the screws into the 2 holes and then place it on the dew shield of your telescope. This system is universal and allows this Bahtinov mask to be mounted on various tubes within the specified diameter range.\u003cbr\u003e This focusing method is much more effective than the Hartmann mask: in fact, light disperses around the 6 holes, whereas the Bahtinov mask, by working on diffraction, avoids dispersion and allows for much more precise focusing. Also for high resolution.\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 fulfilling observation experience.\u003c\/p\u003e\n\n\u003cul style=\"padding-left:20px;\"\u003e\u003cli\u003eTS Optics product for astronomy\u003c\/li\u003e\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 150mm Bahtinov Mask with Screws\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;\"\u003eOther Accessories\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":51120760127704,"sku":"TS Maschera Bahtinov 150mm","price":44.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/0722\/6072\/files\/ba11aadbd7c2bb2a67b00882df51211c.jpg?v=1764071054","url":"https:\/\/www.giordanoastronomia.it\/en\/products\/ts-optics-maschera-di-bahtinov-150mm-con-viti","provider":"Giordano Astronomia","version":"1.0","type":"link"}
