Its design integrates directly with off-axis guiders, providing 12 separate M2.5 threaded points to ensure your guide camera remains perfectly aligned and stable. With native M42, M48, and M28.5 threads, this filter drawer connects to a wide array of correctors, cameras, and telescopes without requiring extensive adapters.\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\u003eDual 1.25\" and 2\" Filter Support in a Single Drawer\u003c\/h3\u003e\n\u003cp\u003eThe SV226P eliminates the need for multiple filter drawers by supporting both 1.25\" and 2\" mounted filters in one holder. This universal design simplifies your setup, reducing the amount of gear you need to manage in the field. To ensure your filters remain secure during slewing and tracking, the drawer uses strong H-type magnets and a side-lock screw, preventing any unwanted movement or tilt that could compromise your images.\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\u003eRigid 12-Point Guide Camera Mounting\u003c\/h3\u003e\n\u003cp\u003eWhen used with an off-axis guider, the stability of the guide camera is critical for sharp, round stars. The SVBONY SV226P provides a robust mounting solution with 12 distinct M2.5 threaded points. This extensive pattern allows for precise, rigid attachment of your guide camera, eliminating the flexure that can ruin long exposures. The entire unit is machined from a single piece of aerospace aluminum, further enhancing its rigidity and ensuring there are no seams to permit light leaks.\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\u003eM42, M48, and M28.5 Thread Compatibility\u003c\/h3\u003e\n\u003cp\u003eVersatility is key to building a functional imaging train. The SV226P includes the most common astronomical threads—M42x0.75 (T-thread), M48x0.75 (2\" filter thread), and M28.5x0.6 (1.25\" filter thread)—to ensure broad compatibility. An included adapter helps bridge these connections, allowing you to easily integrate the filter drawer with flatteners, reducers, cameras, and the OAG itself, maintaining correct spacing and a secure optical path.\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 SVBONY SV226P support both 1.25\" and 2\" filters?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe SVBONY SV226P features a single, versatile filter holder designed to accept either a standard 2\" mounted filter or a 1.25\" mounted filter.

It includes native M48 and M42 threads. You can thread the M48 side directly onto your flattener and the M42 side directly to your camera or T-ring, placing the filter slot conveniently in the optical path while maintaining secure, threaded connections.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eIs the SVBONY SV226P light-tight for long-exposure astrophotography?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes.
