Its f\/5 optical system gathers 44% more light than a 130mm telescope, delivering brighter images of deep-sky objects. The collapsible optical tube, which retracts to just 16 inches, makes this the ideal grab-and-go telescope for dark-sky excursions.\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\u003e150mm f\/5 Optics with 94% Reflectivity\u003c\/h3\u003e\n\u003cp\u003eThe Virtuoso GTi's 150mm borosilicate primary mirror is the core of its imaging capability, providing a Dawes' limit resolution of 0.77 arcseconds. The fast f\/5 focal ratio creates a wide true field of view, perfect for framing large targets like the Andromeda Galaxy (M31) or the Pleiades (M45). Sky-Watcher's 94% reflective aluminum coatings ensure maximum light reaches the eyepiece for bright, high-contrast views.\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\u003eCollapsible Tube: From 27\" to 16\"\u003c\/h3\u003e\n\u003cp\u003eDesigned for ultimate portability, the Virtuoso GTi 150P features a collapsible optical tube that reduces its length from 27 inches down to a compact 16 inches. This allows the 8-pound optical tube to be easily transported and stored. The design maintains collimation well between observing sessions, though both primary and secondary mirrors are fully collimatable for precise optical alignment.\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\u003eWiFi GoTo Control with a 10,000+ Object Database\u003c\/h3\u003e\n\u003cp\u003eIntegrated WiFi transforms your smartphone or tablet into a wireless telescope controller using the free SynScan Pro app for iOS and Android.
