Its helical focuser provides 8mm of fine adjustment travel, while the 1.25-inch connection accepts standard guide cameras and eyepieces, making it a flexible tool for capturing high-quality astrophotos.\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\u003e60mm f\/4 Optics: Brighter Guide Stars, Better Tracking\u003c\/h3\u003e\n\u003cp\u003eThe SV106 features a 60mm aperture and a fast f\/4 focal ratio, a combination that excels at gathering light. This allows your guide camera to detect fainter stars, giving you more options for locking on, especially when imaging in star-poor regions of the sky.
