By letting you tilt the camera slightly, up to about ±9 degrees, in seconds rather than minutes, it breaks up the interference rings that plague etalon-based solar imaging so you can get to a clean image quickly.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe SFT is for solar imagers, especially those shooting hydrogen-alpha and other narrowband setups, who fight Newton's rings and want a fast, controllable way to dial in sensor tilt at the telescope.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features \u0026amp; Design\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFast ±9° tilt:\u003c\/strong\u003e a two-screw adjustment tilts the sensor up to roughly ±9 degrees, letting you clear Newton's rings in seconds instead of fiddling for minutes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM42 threads both ends:\u003c\/strong\u003e M42 × 0.75 threads on both sides drop it into standard imaging trains.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1.25″ adapters included:\u003c\/strong\u003e a 1.25″ holder and 1.25″ T-mount are provided for flexible connection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact aluminum body:\u003c\/strong\u003e a 15 mm-thick Aluminum 6061-T6 body adds only 40 mm of total optical length.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eRecommended Uses\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eUse the Solar Fast Tilter for narrowband solar imaging, particularly hydrogen-alpha work with etalons, where Newton's rings appear and a small, quickly adjustable sensor tilt cleans up the image.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eCompatibility \u0026amp; Accessory Notes\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnections:\u003c\/strong\u003e M42 × 0.75 on both ends, plus the included 1.25″ holder and T-mount, integrate it with common solar imaging trains.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBackfocus:\u003c\/strong\u003e it adds 40 mm of optical length, so confirm your setup can still reach focus; for example, Player One notes the Lunt 40 does not have enough travel to reach focus with the SFT in place.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eGood to Know Before You Order\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThe SFT adds 40 mm of path length, so some short-tube solar scopes (Player One cites the Lunt 40) may not reach focus with it installed; check your available backfocus.\u003c\/li\u003e\n\u003cli\u003ePlayer One does not publish a weight for the SFT; contact us if you need it for balancing a specific rig.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eFAQ\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eIs it difficult to set up?\u003c\/strong\u003e No. It threads into your imaging train via M42 (or the included 1.25″ adapters), and you set tilt with two screws; clearing Newton's rings takes seconds.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are Newton's rings and why does tilt help?\u003c\/strong\u003e They are concentric interference rings that form in narrowband solar imaging; tilting the sensor a few degrees off-perpendicular breaks up the interference so the rings disappear.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow much can it tilt?\u003c\/strong\u003e About ±9 degrees, controlled by two adjustment screws.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eBottom Line\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe Solar Fast Tilter gives solar narrowband imagers a quick, repeatable ±9° sensor tilt to eliminate Newton's rings without a lengthy fiddle at the eyepiece end.\u003c\/p\u003e","brand":"Player One Astronomy","offers":[{"title":"Default Title","offer_id":44014079344751,"sku":"SFT","price":179.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/SFT-3-1024x999__54466.jpg?v=1766570059","url":"https:\/\/ontariotelescope.com\/products\/solar-fast-tilter","provider":"Ontario Telescope and Accessories","version":"1.0","type":"link"}
