It replaces traditional guide scope rings with a backlash-free mechanical system, providing independent altitude and azimuth control for perfect alignment with your main telescope's field of view.\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\u003eStronghold Tangent Assembly: Precision Pointing for Heavy Optics\u003c\/h3\u003e\n\u003cp\u003eFor serious imaging, simply mounting a guide scope in a set of rings is often not stable enough. The Stronghold Tangent Assembly solves this by providing a rigid, zero-flexure platform controlled by two oversized adjustment knobs. This allows you to make minute, smooth corrections to the pointing of your guide scope, finder, or telephoto lens without introducing any sag or backlash.\u003c\/p\u003e\n\u003cp\u003eThis level of control is critical for tasks like drift alignment, where you need to precisely center a star in your guide camera, or for framing a guide star that is far off-axis from your primary imaging target. The robust, all-metal construction ensures that once you lock your alignment, it stays locked all night.\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\"\u003eWhat is the primary function of the Baader Stronghold Tangent Assembly?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe Stronghold Tangent Assembly is designed to hold and precisely aim a secondary instrument, such as a \u003cstrong\u003eguide scope, finder scope, or a camera with a telephoto lens\u003c\/strong\u003e, parallel to your main telescope. It provides fine, geared adjustments in altitude and azimuth (up\/down and left\/right) for exact alignment.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow does the Stronghold Tangent Assembly improve polar alignment with a guide scope?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eFor precise drift alignment, you need to accurately measure the drift of a star near the celestial equator and meridian. The Stronghold allows you to move your guide scope's field of view independently of the main telescope, making it easy to center the ideal alignment star without moving your entire mount. This makes the process faster and more accurate.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I use the Stronghold Tangent Assembly to aim a heavy guide scope?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes. The Stronghold is specifically engineered for stability and is an ideal solution for mounting heavier guide scopes or telephoto lenses that would cause flexure in standard guide rings. Its rigid, all-metal design prevents the secondary instrument from shifting during an imaging session, which is a common source of elongated stars.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eIs the Baader Stronghold Tangent Assembly compatible with standard dovetail bars?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, the Baader Stronghold is designed to be a versatile part of a larger mounting system.
