His idea was to mount a Newton telescope on an easy-to-use alt-azimuth mount that does not need time-consuming alignments. Sky-Watcher improved the Dobson design building a collapsible system that allows the telescope to be easily stored or transported. The 3 metal bars, used to fully extend the tube, have an auto-lock spring loaded system that simplify the set up of the telescope so only one person is required to fully extend the tube. The rigidity of the telescope keeps the mirrors collimated and the tension control system keeps the telescope balanced, so it is not necessary to move heavy counterweights.\u003c\/p\u003e\n\u003cp\u003eJust extend the tube, use the finderscope and point the telescope towards your favourite night sky objects sit back and enjoy the great light gathering of the Sky-Watcher Dobsonian!\u003c\/p\u003e\n\u003cp\u003eTo top it off, the Sky-Watcher Collapsible Dobsonians are equipped with a 2 Crayford focuser and focuser locking screw.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAccessories in the Box:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFinderscope 9X50 straight version\u003c\/li\u003e\n\u003cli\u003eEyepiece 1.25 Super Plossl 25mm (48x) apparent field of view 52ø\u003c\/li\u003e\n\u003cli\u003eEyepiece 1.25 Super Plossl 10mm (120x) apparent field of view 52ø\u003c\/li\u003e\n\u003cli\u003eEyepiece adapter from 2 to 1.25 with M42 thread\u003c\/li\u003e\n\u003cli\u003e2 tube extension\u003c\/li\u003e\n\u003cli\u003eUser Manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eSWDOB254C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptical Design\u003c\/td\u003e\n\u003ctd\u003eNewtonian (parabolic primary mirror)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAperture\u003c\/td\u003e\n\u003ctd\u003e254mm (10)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocal Length\u003c\/td\u003e\n\u003ctd\u003e1200mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocal Ratio\u003c\/td\u003e\n\u003ctd\u003ef\/4.7\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSecondary mirror diameter\u003c\/td\u003e\n\u003ctd\u003e58mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eObstruction\u003c\/td\u003e\n\u003ctd\u003e22.8%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolving Power\u003c\/td\u003e\n\u003ctd\u003e0.47\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStellar Limit Magnitude\u003c\/td\u003e\n\u003ctd\u003e15.1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHighest Practical Magnification\u003c\/td\u003e\n\u003ctd\u003e508X\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight gathering power (compared to the unaided eye)\u003c\/td\u003e\n\u003ctd\u003e1317X\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocuser\u003c\/td\u003e\n\u003ctd\u003e2 Crayford with 1.25 adaptor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTelescope tube length\u003c\/td\u003e\n\u003ctd\u003e805mm-1120mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTelescope height\u003c\/td\u003e\n\u003ctd\u003e1390mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBase diameter\u003c\/td\u003e\n\u003ctd\u003e520mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTelescope tube weight\u003c\/td\u003e\n\u003ctd\u003e14kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Jacobs Digital","offers":[{"title":"Default Title","offer_id":50533183651928,"sku":"SWDOB250C","price":1974.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0669\/9388\/1176\/files\/swdob250c-47-c531535a-fcd2-4e74-807c-04176c64881a_2983f6f1-d40e-45d3-a8ee-f7aec3a17c9a.jpg?v=1790277643","url":"https:\/\/buykiwi.co.nz\/products\/skywatcher-10-250mm-collapsible-dobsonian-telescope","provider":"Buy Kiwi","version":"1.0","type":"link"}
