By making incredibly small, smooth adjustments with the fine-focus knob, you can dial in perfect focus without causing the primary mirror to tilt. While it doesn't change the telescope's core mechanics, it gives you the control needed to work around the inherent limitations of the design, keeping your target centered and stable for sharp, frustration-free observing and imaging.\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 Feather Touch Micro Focuser for the Meade 14.0\" SCT reduce image shift?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eImage shift is caused by the primary mirror tilting as it moves.

astrophotography. By replacing traditional Crayford friction drives with a diamond-coated, geared track, this focuser provides positive, repeatable mechanical engagement. This design ensures that heavy imaging trains—including large cameras, filter wheels, and off-axis guiders—can be brought to a critical focus and held there securely throughout an imaging session.\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\u003eThe Diamond Steeltrack Drive: Zero-Slip Focusing for Heavy Payloads\u003c\/h3\u003e\n\u003cp\u003eUnlike a standard Crayford focuser that relies on simple friction between a steel shaft and an aluminum drawtube, the Diamond Steeltrack system uses a fundamentally different approach. The drive shaft engages with a diamond-coated steel track, creating a micro-geared surface that prevents the slippage common with heavy or off-axis loads. This positive engagement means focus is maintained even when the telescope is pointed near the zenith, where gravity exerts maximum pull on the imaging train.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo Slippage:\u003c\/strong\u003e The micro-geared track provides a direct, mechanical connection, delivering precise, repeatable focuser movement without the risk of slipping under load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Load Capacity:\u003c\/strong\u003e Engineered specifically for modern astrophotography, the drive system can handle significant weight without compromising focus accuracy.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurability:\u003c\/strong\u003e The hardened steel and diamond-coating of the drive components resist wear and indentation, ensuring long-term reliability and consistent feel.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eA Rigid 2-inch Drawtube for Demanding Imaging Trains\u003c\/h3\u003e\n\u003cp\u003eFlexure in the optical train is a primary source of elongated or misshapen stars, especially in the corners of the frame.

Telescopes\u003c\/h2\u003e\n\u003cp\u003eThe Baader Diamond Steeltrack 2\" Focuser is a fundamental upgrade for any Schmidt-Cassegrain or EdgeHD telescope, replacing the often-problematic stock focuser with a high-precision, zero-slip mechanism. It connects directly to both standard 2\" and large-format 3.3\" rear cell threads, providing a robust platform that completely eliminates mirror shift during critical focusing operations.\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\u003eNative Fit for 2\" and 3.3\" SC\/HD Threads\u003c\/h3\u003e\n\u003cp\u003eThis Diamond Steeltrack focuser is engineered specifically for the Schmidt-Cassegrain ecosystem. It includes the necessary adapters to thread directly onto the rear cell of virtually any modern SCT, from smaller 6\" and 8\" models with 2\" threads to larger 9.25\", 11\", and 14\" instruments that use the larger 3.3\" thread standard.\u003c\/p\u003e\n\u003cp\u003eThe benefit of this external focuser is the immediate elimination of mirror shift—the slight image movement caused by the primary mirror tilting on its baffle during focusing. By locking the primary mirror and using the Diamond Steeltrack for fine adjustments, you ensure your target remains perfectly centered, a requirement for high-magnification planetary imaging and autoguiding.\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\u003eThe 2\" Diamond Steeltrack Drive: Zero-Slip Load Bearing\u003c\/h3\u003e\n\u003cp\u003eAt the heart of the focuser is the Diamond Steeltrack drive system. Unlike friction-based Crayford focusers, this design uses a hardened stainless steel drive shaft that meshes with ball bearings running on a polished steel track. This positive, non-slip engagement ensures the 2\" drawtube holds its position perfectly, even when loaded with heavy imaging trains.\u003c\/p\u003e\n\u003cp\u003eWhether you're using a heavy 2\" eyepiece, a large diagonal, or a full imaging setup with a camera, filter wheel, and off-axis guider, the Steeltrack drive will not flex or slip. This stability is critical for maintaining focus throughout a long imaging session, especially when the telescope is pointed near the zenith where gravity exerts maximum pull on the drawtube.\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\u003eSteeltrack vs. Crayford: Solving Focuser Slip in SC\/HD Imaging\u003c\/h3\u003e\n\u003cp\u003eWhile a standard Crayford focuser offers smooth motion, its reliance on friction is a known weak point for serious imaging with an SCT. Under heavy loads, a Crayford can slip, causing a sudden focus shift that can ruin an exposure. This is a problem the Diamond Steeltrack design was built to solve.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrayford Focuser:\u003c\/strong\u003e A smooth, round shaft presses against a flat plate on the drawtube.

You first use the original SCT knob to achieve a rough focus, and then you lock the primary mirror in place (if your scope has mirror locks). From that point on, all fine focusing is done exclusively with the Baader Diamond Steeltrack, which ensures stability and prevents any further mirror movement.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I motorize the Baader Diamond Steeltrack focuser?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, the Diamond Steeltrack is designed for easy motorization. Baader Planetarium offers the SteelDrive II motor system, which attaches directly to the focuser for precise, computer-controlled focusing. This is a popular upgrade for remote and automated imaging setups.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWill the Baader Diamond Steeltrack handle my heavy camera setup for imaging Jupiter with a Celestron C11 EdgeHD?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eAbsolutely. This is exactly the scenario the Diamond Steeltrack is built for. The C11 EdgeHD has the large 3.3\" rear thread, which this focuser fits natively. Its zero-slip drive system can easily support a heavy planetary imaging camera, filter wheel, and Barlow lens without flexing or slipping, ensuring you maintain critical focus on Jupiter's cloud bands throughout your capture session.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eI have a Meade 8\" LX200.

The Meade 8\" scope typically uses the 2\" rear thread, so the included adapter will provide a secure connection. When imaging a bright target like the Hercules Cluster (M13), achieving perfect focus on the dense core is critical. By locking the primary mirror and using the Diamond Steeltrack, you eliminate mirror shift, ensuring your guide star doesn't move and your long exposures remain sharp across the

It is an ideal match for observatory-class refractors, large astrographs like the Takahashi FSQ-106, and custom Ritchey-Chrétien telescopes that use large format sensors and heavy imaging trains. Its high payload capacity makes it unsuitable for smaller, portable setups where weight is a primary concern.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow does the ARCO 3\" rotator work as a field de-rotator?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eWhen used with a telescope on an \u003cstrong\u003ealt-azimuth mount\u003c\/strong\u003e, the sky appears to rotate around the center of the field of view. The ARCO 3\", controlled by appropriate software, precisely counter-rotates your camera at the sidereal rate to cancel this effect.

A single USB cable runs from your computer or hub to the ESATTO 4\" focuser. A short, included cable then connects the ESATTO to the ARCO 3\" rotator, delivering both power and commands and eliminating two long cable runs.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I use the ARCO 3\" rotator to perfectly frame targets like the Horsehead Nebula (B33)?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes. This is a primary function of the ARCO 3\" on an equatorial mount. After your mount slews to the target, you can use the rotator's high-resolution control to make fine rotational adjustments to your camera. This ensures you can achieve the exact composition you want for targets with specific orientations, like the Horsehead and Flame Nebula region, without having to physically rotate the entire imaging train.\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\u003cli\u003e\n\u003cul class=\"DAV-grid\"\u003e\n\u003cli class=\"DAV-grid-item\"\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0753\/5280\/1565\/files\/PrimaLuceLab_ESATTO_Manual.pdf\" target=\"_blank\"\u003e\u003csvg class=\"DAV-img-box\" viewbox=\"0 0 512 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"\u003e\u003cpath d=\"M0 64C0 28.7 28.7 0 64 0L224 0l0 128c0 17.7 14.3 32 32 32l128 0 0 144-208 0c-35.3 0-64 28.7-64 64l0 144-48 0c-35.3 0-64-28.7-64-64L0 64zm384 64l-128 0L256 0 384 128zM176 352l32 0c30.9 0 56 25.1 56 56s-25.1 56-56 56l-16 0 0 32c0 8.8-7.2 16-16 16s-16-7.2-16-16l0-48 0-80c0-8.8 7.2-16 16-16zm32 80c13.3 0 24-10.7 24-24s-10.7-24-24-24l-16 0 0 48 16 0zm96-80l32 0c26.5 0 48 21.5 48 48l0 64c0 26.5-21.5 48-48 48l-32 0c-8.8 0-16-7.2-16-16l0-128c0-8.8 7.2-16 16-16zm32 128c8.8 0 16-7.2 16-16l0-64c0-8.8-7.2-16-16-16l-16 0 0 96 16 0zm80-112c0-8.8 7.2-16 16-16l48 0c8.8 0 16 7.2 16 16s-7.2 16-16 16l-32 0 0 32 32 0c8.8 0 16 7.2 16 16s-7.2 16-16 16l-32 0 0 48c0 8.8-7.2 16-16 16s-16-7.2-16-16l0-64 0-64z\" fill=\"#0047a7\"\u003e\u003c\/path\u003e\u003c\/svg\u003e\n\u003cdiv\u003e\n\u003cp class=\"DAV-item-title\"\u003eDownload Manual\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/davidastro.com\/pages\/primalucelab-warranty-policy\" rel=\"noopener\" target=\"_blank\"\u003ePrimaLuceLab 1-Year Warranty\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PrimaLuceLab","offers":[{"title":"Default Title","offer_id":44967966867741,"sku":"PLL-PLLEST4ARCO3","price":4109.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/5280\/1565\/products\/esatto-4-focuser-with-arco-3-rotator__54024.1641495402.1280.1280.jpg?v=1684347354"}],"url":"https:\/\/davidastro.com\/collections\/focusers.oembed?page=4","provider":"David Astro","version":"1.0","type":"link"}
