If so, you may have encountered a common problem known as image shift - or difficulty achieving perfect focus. Oceanside Photo and Telescope is here to help with the TPO Dual Speed SCT Crayford Focuser.\u003c\/p\u003e\n\u003cp\u003eIn order to pass savings along to our customers, TPO engages the services of a leading manufacturer to custom CNC machine these specialty 2 inch Dual Speed Crayford Focusers meant specifically for the Schmidt Cassegrain Telescope. Aluminum means lightweight, and from there they are then black anodized for good looks and durability. These focusers are designed to fit almost every model SCT - including Meade and Celestron - and are compatible with any standard SCT thread.\u003c\/p\u003e\n\u003cp\u003eIf you're unsure of the fit, just check your telescope's rear cell for an approximate 2 inch diameter male thread, or contact our experts to insure a perfect match. Inside the TPO 1:10 Dual Speed SCT Crayford Focuser, you'll find anti-reflection baffles and coatings to keep any stray light to a minimum and provide the best contrast possible. Precision roller bearings incorporated into the tube design allow for smooth functioning on the roller shaft and the black anodized barrel is laser-etched with a millimeter scale to give you 100% precise calibration markings. The focusers stops where you want it to... and stays put.\u003c\/p\u003e\n\u003cp\u003eThe TPO 1:10 Dual Speed SCT Crayford Focuser will also allow up to 1 inch of focus travel, too! There's no harsh aluminum screws here to scratch eyepiece barrels. The TPO 1:10 Dual Speed SCT Crayford Focuser uses only brass compression ring fittings that gently cradle your prized eyepieces or 2 inch star diagonals with a secure fit that you'd expect from high quality. As an added bonus, we've included a 1.25 inch to 2 inch adapter, too... So all of your accessories are good right out of the box!\u003c\/p\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cspan style=\"color: #ff0000;\"\u003e\u003cstrong\u003eTPO 2 inch Dual Speed SCT Crayford Focuser Features \u003c\/strong\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003eMinimum focuser height without 1.25 inch adapter: 4.29 inches or 109 mm.\u003c\/li\u003e\n\u003cli\u003eMinimum focuser height with 1.25 inch adapter: 5.28 inches or 134 mm.\u003c\/li\u003e\n\u003cli\u003eMaximum focuser height without 1.25 inch adapter\u0026gt; 4.88 inches or 124 mm.\u003c\/li\u003e\n\u003cli\u003eTube Travel Length: 0.99 inches or 25 mm\u003c\/li\u003e\n\u003cli\u003eFocuser Weight (including 1.25 inch adapter): 1 lb-10.5 oz or 751 gm\u003c\/li\u003e\n\u003cli\u003eDiameter of Focus Knob: 1.57 inches or 40 mm\u003c\/li\u003e\n\u003cli\u003eDiameter of Micro-focus Knob: 1.02 inch or 26 mm\u003c\/li\u003e\n\u003cli\u003eOuter Barrel Diameter: 3.3 inches or 84 mm\u003c\/li\u003e\n\u003cli\u003eStandard SCT Female Thread\u003c\/li\u003e\n\u003cli\u003eCalibrated Millimeter Markings on Focuser Outer Tube\u003c\/li\u003e\n\u003cli\u003e360 Degree Fully Rotatable\u003c\/li\u003e\n\u003cli\u003eDust Plug Included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!-- split --\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned for Schmidt Cassegrain telescopes to fit all standard SCT rear threads.\u003c\/li\u003e\n\u003cli\u003eThe \u003cb\u003eTPO 2 inch Dual Speed SCT Crayford Rear Focuser\u003c\/b\u003e is custom machined from aluminum and black anodized for good looks and durability.\u003c\/li\u003e\n\u003cli\u003e1:10 speeds work for visual applications through astrophotography and rotates a full 360 degrees.\u003c\/li\u003e\n\u003cli\u003eThe \u003cb\u003eTPO 2 inch Dual Speed SCT Crayford Rear Focuser\u003c\/b\u003e permits use of 2 inch accessories.\u003c\/li\u003e\n\u003cli\u003eIncludes 1.25 inch adapter.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TPO","offers":[{"title":"Default Title","offer_id":52488977154343,"sku":"fsr1793368160729","price":117.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/2481\/4887\/files\/tpo-2-sct-focuser---crayford-dual-speed_1.jpg?v=1793368169","url":"https:\/\/mobwifestyleboutique.shop\/products\/tpo-2-sct-focuser-crayford-dual-speed","provider":"My Store","version":"1.0","type":"link"}
