Its all-metal body provides a zero-flex fit in any 1.25\" focuser, making it a reliable tool for quickly collimating Newtonian reflectors, SCTs, and even refractors in the field.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eAchieve Perfect Collimation with a Locked 1.25\" Laser Path\u003c\/h3\u003e\n\u003cp\u003eThe core of the SV121 is its upgraded triangular screw structure, which firmly locks the laser's optical path. This design prevents the beam from shifting between uses, ensuring that once the collimator itself is calibrated, it stays that way. For you, this means consistent, repeatable alignment accuracy every time you collimate, eliminating the guesswork and saving valuable observing time.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eField-Ready 1.25\" Design with Angled Plate \u0026amp; Adjustable Brightness\u003c\/h3\u003e\n\u003cp\u003eThe SV121 is built for practical use under the stars. An angled aluminum plate reflects the returning laser spot, allowing you to see it clearly while making adjustments to your primary mirror. For added flexibility, the laser's brightness is adjustable, providing optimal visibility in both bright daylight and complete darkness.\u003c\/p\u003e\n\u003cp\u003eIts all-metal body features a sandblasted, anodized finish for corrosion resistance and durability. The standard 1.25\" barrel includes dual rubber rings and a micro-angle end to compensate for focuser tolerances, creating a snug, wobble-free fit that is critical for accurate collimation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow does the SV121 Laser Collimator's locking system improve accuracy?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe Svbony SV121 uses a triangular screw system to firmly lock the laser diode in place. This prevents the laser beam from shifting or losing its own alignment, which is a common problem in simpler collimators. The result is a highly consistent and reliable tool that gives you the same precise starting point every time you collimate your telescope.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eIs the Svbony SV121 compatible with my 8\" f\/5 Newtonian telescope?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, absolutely. The SV121 is ideal for collimating Newtonian reflectors like an 8\" f\/5. It fits directly into a standard 1.25\" focuser, and its adjustable brightness and angled viewing screen make it easy to align both the secondary and primary mirrors for sharp, high-contrast views.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I use the SV121 Laser Collimator with a Schmidt-Cassegrain Telescope (SCT)?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, the Svbony SV121 can be used to collimate an SCT. While SCTs are often collimated on a real star, a laser collimator provides an excellent way to achieve a very close alignment indoors before you head out. This makes the final star-test tweaking much faster and easier.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the benefit of the SV121's adjustable brightness?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eAdjustable brightness allows the Svbony SV121 to adapt to any lighting condition. You can turn the brightness up for easy visibility during daytime collimation or turn it down to a dim setting at a dark sky site to preserve your night vision while making fine adjustments.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eDoes the SV121 fit in a 2\" focuser?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe Svbony SV121 has a native 1.25\" barrel. To use it in a 2\" focuser, you will need a standard \u003cstrong\u003e2\" to 1.25\" adapter\u003c\/strong\u003e, which is a common accessory included with most telescopes that have 2\" focusers. The collimator itself is fully compatible when used with such an adapter.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhy is a tight fit in the focuser important for a laser collimator like the SV121?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eA tight, wobble-free fit is critical because any \"slop\" or movement of the collimator in the focuser will change the direction the laser is pointing. This introduces error and makes an accurate alignment impossible. The Svbony SV121's design incorporates features to ensure a snug fit, eliminating this source of error and leading to a more precise collimation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ctable class=\"DAV-specifications\"\u003e\n\u003ctbody\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cul class=\"DAV-grid\"\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\n\u003cli\u003e\n\u003ca href=\"https:\/\/davidastro.com\/pages\/svbony-warranty-policy\" rel=\"noopener\" target=\"_blank\"\u003eSVBONY Warranty Policy\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SVBONY","offers":[{"title":"Default Title","offer_id":52861237887261,"sku":"SV-F9192A","price":39.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/5280\/1565\/files\/SVBONY-SV121-Laser-Collimator-1_cab61d90-fe12-4489-a215-d1f9677aa40a.jpg?v=1788660443","url":"https:\/\/davidastro.com\/fr\/products\/svbony-sv121-red-laser-collimator-125in","provider":"David Astro","version":"1.0","type":"link"}
