The SV149 adapter allows you to attach a 1.25\" planetary camera, guide camera, or eyepiece directly to a Canon EF or EF-S lens, effectively turning it into a portable, wide-field refractor. This is an ideal solution for creating a compact grab-and-go imaging rig for capturing large targets like the Andromeda Galaxy (M31) or the North America Nebula (NGC 7000).\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 Construction at a Compact 122g\u003c\/h3\u003e\n\u003cp\u003eEngineered from a single piece of aluminum alloy, the SV149 ensures a secure, flex-free connection between your heavy lens and sensitive camera.
