We can now offer an excellent high-end focuser at an incredible price. The rack and pinion drive system: A simple Crayford focuser works by pressure. The load on the drive shaft exerts pressure on the ball bearings and reduces the smoothness of operation. Our RPA focuser is driven by a rack and pinion guide and has no ball bearings: this has the advantage of separating the guide and bearing sections. Even under heavy loads, it can be operated smoothly with fine movements. The locking mechanism has also been improved. It is not a simple screw that exerts pressure on the drawtube, but a fixed position of the drive system. This ensures that the focus position is perfectly maintained. Self-centering 2\" and 1.25\" reducers: Since simple locking screws do not allow for friction locking, the 2\" and 1.25\" reducers are locked by a force-fit connection. Likewise, they are always perfectly centered.\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\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 PHOTOLINE 2.5-inch Deluxe Rack and Pinion Focuser for Astrophotography\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;\"\u003eFocusers\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":51120853582040,"sku":"RPA25","price":378.3,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/0722\/6072\/files\/cdbba68f0cb043ad1c1ad1ba5a936016.jpg?v=1764072849","url":"https:\/\/www.giordanoastronomia.it\/en\/products\/ts-optics-photoline-2-5-pollici-deluxe-rack-and-pinion-focuser-for-astro-imagers","provider":"Giordano Astronomia","version":"1.0","type":"link"}
