This single-piece aluminum alloy adapter weighs just 137g and features a standard M52*0.75 thread, providing a secure, rigid connection between your high-quality camera optics and any standard 1.25\" telescope focuser. With dimensions of 78*58*60mm, it integrates easily into your existing imaging train without adding significant weight or leverage to the drawtube.\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\u003eCNC-Machined Aluminum Construction at 137g\u003c\/h3\u003e\n\u003cp\u003eEngineered from a single block of black anodized aluminum alloy, the SV149 adapter ensures a stable, flex-free connection.

You would attach your 135mm Nikon AF lens to the SV149, insert the adapter into your telescope's 1.25\" focuser, and then place your 1.25\" astronomy camera into the focuser. This setup piggybacks on your main telescope mount for tracking, using the camera lens as a dedicated wide-field astrograph.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I use the SV149 adapter and my Nikon lens as a guidescope on my 10\" Dobsonian?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, this is an excellent application.
