Constructed from black aluminum alloy, the 350g adapter features M42*0.75 T-threads for a secure camera connection and M28.5*0.6 threads to accommodate standard 1.25\" astronomy filters.\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\u003e42mm Variable Projection: Dial in Your Magnification\u003c\/h3\u003e\n\u003cp\u003eThe core feature of the SV112 is its ability to vary the distance between your camera sensor and an inserted eyepiece, with a maximum extension of 42mm. Sliding the barrel allows you to fine-tune the final magnification, letting you frame planetary targets or small nebulae perfectly without changing eyepieces. A laser-engraved scale provides repeatable settings, while the machined grip ring ensures you can make adjustments securely, even with gloves on.\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\u003ePrime Focus \u0026amp; Eyepiece Projection for 1.25\" Focusers\u003c\/h3\u003e\n\u003cp\u003eThis adapter enables two fundamental types of astrophotography. For prime focus imaging, you connect your camera directly to the telescope without an eyepiece, turning your telescope into a massive telephoto lens ideal for capturing wide-field targets like the Orion Nebula (M42) or the Andromeda Galaxy (M31). For high-magnification views of the Moon and planets, insert a 1.25\" eyepiece (up to 42mm in outer diameter) into the adapter for eyepiece projection, dramatically increasing your effective focal length.\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\u003eAll-Metal Build: 350g of Aluminum with M28.5 Filter Threads\u003c\/h3\u003e\n\u003cp\u003eWeighing a solid 350g, the SV112 is machined from aluminum alloy for durability and rigidity, preventing flexure in your imaging train.
