The truss structure is compact, allowing for easy transportation while you're in search of the perfect dark, pristine sky. The outstanding light gathering of the mirror and the superior resolution allow amazing journeys through the universe, offering spectacular observations of tangled gas filaments in nebulae, fine galaxy details and remarkable planet structures. Despite the size of the mirror, the telescope is easy to assemble following the step by step instructions and video.\u003c\/p\u003e\n\u003cp\u003eTo top it off, the Sky-Watcher Stargate is equipped with a 2\" Crayford dual speed focuser for smooth and precise focusing, and a focuser-locking screw.\u003c\/p\u003e\n\u003ch3\u003eParabolic Primary Mirror\u003c\/h3\u003e\n\u003cp\u003eThe most extraordinary feature of the Stargate is the technology used in the mirrors. They are made up of borosilicate glass that has a very low expansion coefficient, reducing the stresses caused by thermal gradients. The primary mirror uses a special lightweight technology. In fact, the mirror is extremely light and thin, but the glass ribs beneath minimise the glass deformation, thus allowing continuous high performance in all the telescope angulations. Moreover, the small thickness of the mirror allows a much quicker cooling time compared to the standard monolithic mirrors. The secondary mirror has a honeycomb structure that follows the concept of the primary mirror: lightweight, rigid and quick to cool down.\u003c\/p\u003e\n\u003cp\u003eBoth the mirrors are aluminised and in order to protect the reflective treatment over the years, the coatings are protected by a thin layer of quartz (silicon dioxide). This protection is needed as the mirrors are exposed to external elements due to their position in an open truss tube. Sky-Watcher is one of the few companies in the world that use this particular technology.\u003c\/p\u003e\n\u003ch3\u003eComputerised Synscan\u003c\/h3\u003e\n\u003cp\u003eThe Stargate Go-To is equipped with the Sky-Watcher SynScan that has in it's memory 42,900 objects! Once the telescope is aligned, thousands of objects will be visible with a touch of a button; planets, the entire Messier catalogueue, bright and double stars and the IC, NGC, SAO catalogueues. In addition to this, the Deep Sky Tour function suggests a list of the most interesting deep sky objects so even the inexperienced astronomer can easily observe faint nebulae and galaxies.\u003c\/p\u003e\n\u003cp\u003eThe Freedom Find technology (dual-encoder) allows the telescope to be moved manually whenever the user wishes, but without losing any of the pre-set alignment.\u003c\/p\u003e\n\u003ch3\u003eKey Features:\u003c\/h3\u003e\n\u003cp\u003eIntermediate To Professional User\u003c\/p\u003e\n\u003cp\u003eCollapsible Transportable Dobsonian\u003c\/p\u003e\n\u003cp\u003eView Moon Planets and Galaxies\u003c\/p\u003e\n\u003cp\u003eTruss Tube with Clamps\u003c\/p\u003e\n\u003cp\u003eBorosilicate Aluminised Mirrors\u003c\/p\u003e\n\u003cp\u003eQuartz-Coated Mirror Protection\u003c\/p\u003e\n\u003cp\u003eAluminium Structure and Base\u003c\/p\u003e\n\u003cp\u003eDiffraction-Limited Parabolic Mirror\u003c\/p\u003e\n\u003cp\u003eUltra-Thin Secondary Mirror Support\u003c\/p\u003e\n\u003cp\u003e2.5 mm Secondary Support\u003c\/p\u003e\n\u003cp\u003eM42 Thread DSLR Connection\u003c\/p\u003e\n\u003ch3\u003eWhat's in the Box:\u003c\/h3\u003e\n\u003cp\u003eSkyWatcher 20\" Dobsonian GoTo Collapsible Newtonian Telescope Stargate 500P (SynScan HC)\u003c\/p\u003e\n\u003cp\u003eSynscan Hand Controller with Cables\u003c\/p\u003e\n\u003cp\u003e12v Power Cable with Lighter Socket Plug\u003c\/p\u003e\n\u003cp\u003eFinderscope 9x50 Straight Version\u003c\/p\u003e\n\u003cp\u003eEyepiece 2\" Let 28mm (71x) - Apparent Filed of View 56°\u003c\/p\u003e\n\u003cp\u003eEyepiece 1.25\" Super Plossl 10mm (200x) - Apparent Filed of View 52°\u003c\/p\u003e\n\u003cp\u003eEyepiece Adapter from 2\" To 1.25\" with M42 Thread\u003c\/p\u003e\n\u003cp\u003e2\" Tube Extension\u003c\/p\u003e\n\u003cp\u003eCollimation Eyepiece\u003c\/p\u003e\n\u003cp\u003eUser Manual\u003c\/p\u003e","brand":"SkyWatcher","offers":[{"title":"Default Title","offer_id":47296541065383,"sku":"GC39-SWDOB500CGT","price":14998.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/4083\/0375\/files\/GC39-SWDOB500CGT.jpg?v=1763530190","url":"https:\/\/www.georges.com.au\/products\/skywatcher-20-dobsonian-goto-collapsible-newtonian-telescope-stargate-500p-synscan-hc","provider":"Georges Cameras","version":"1.0","type":"link"}
