This adapter uses the universal M42 T-thread standard, allowing it to connect cameras, filter wheels, and correctors that require fine spacing adjustments within its 5mm of travel.\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\u003ePrecision Spacing Control from 15mm to 20mm\u003c\/h3\u003e\n\u003cp\u003eAchieving the correct distance between a field flattener or reducer and the camera sensor is critical for sharp, coma-free stars across the entire image. This variable adapter simplifies the process, replacing a collection of fixed-length spacers with a single, adjustable unit. By twisting the adapter, you can dial in any length between 15mm and 20mm, then lock it securely in place. This allows you to fine-tune your spacing to match the exact requirements of your optical system. For different spacing needs, Starizona also offers 20-30mm and 30-40mm versions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the adjustment range of the Starizona Variable T-Threaded Adapter?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThis specific model of the Starizona Variable Adapter allows for a continuous adjustment of its length from \u003cstrong\u003e15mm to 20mm\u003c\/strong\u003e.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat threads does the Starizona 15-20mm Variable Adapter use?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe adapter uses standard male and female \u003cstrong\u003eM42 (T2) T-threads\u003c\/strong\u003e, making it compatible with a wide range of astronomy cameras, filter wheels, off-axis guiders, and other T-threaded accessories.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eAre other adjustment ranges available for the Starizona Variable M42 Adapter?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes.
