The tube is supplied with carbon connecting rods, which on the one hand are light weight but also have a favorable expansion behavior resulting from changing temperatures. The tube weight is around 30kg and the tube comes with a Losmandy-level dovetail rail on both sides. With a length of approx. 1140mm, the 14\" RC is still suitable for compact private or professional observatories.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe 14\" f\/8 RC astrograph illuminates about 70 mm field very well and without a corrector lens, a field with a diameter of approx. 35 mm with very good correction is available.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cem\u003eThe advantages of TS-Optics RC telescopes at a glance:\u003c\/em\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eHyperbolic primary mirror and secondary mirror for a large fully corrected field of view.\u003c\/li\u003e\n\u003cli\u003eAstrophotography with camera sensors up to 30 mm in diameter is also possible without a corrector.

To shoot directly in focus, you'll need the M117 x 1 extension sleeves that are included. These are screwed between the telescope and the focuser and thus reduce the back focus. The generous back focus also allows the connection of correctors, which we recommend when using use of full-frame sensors.\u003c\/p\u003e\n\u003cp\u003eYou can also connect a focal length reduction, which further increases the light intensity by reducing the f ratio. You can clamp the camera directly via the 2\" receptacle or you can screw everything via the threads of the focuser.\u003cbr data-mce-fragment=\"1\"\u003eSuitable adapters can be found in the accessories area.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cstrong\u003eTelescope Specs:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOptics: RC Ritchey Chretien Optics\u003c\/li\u003e\n\u003cli\u003eAperture: 355mm \/ 14\"\u003c\/li\u003e\n\u003cli\u003eFocal length: 2845mm\u003c\/li\u003e\n\u003cli\u003eAperture ratio: f\/8\u003c\/li\u003e\n\u003cli\u003eReflection: 99% reflection on main and secondary mirrors\u003c\/li\u003e\n\u003cli\u003eConnection eyepiece side: 2\" and 1.25\" receptacle\u003c\/li\u003e\n\u003cli\u003eAdditional thread: M77x0,75 female thread on the pull-out tube and M74x0,75 male thread\u003c\/li\u003e\n\u003cli\u003eBack focus: 280 mm from the back of the tube\u003c\/li\u003e\n\u003cli\u003eTube diameter: 535 mm\u003c\/li\u003e\n\u003cli\u003eTube length: 1140 mm with, 990 mm without focuser\u003c\/li\u003e\n\u003cli\u003eWeight: 30 kg\u003c\/li\u003e\n\u003cli\u003eShading by secondary mirrors: approx. 170 mm\u003c\/li\u003e\n\u003cli\u003ePrism rails: 2x Losmandy level\u003c\/li\u003e\n\u003cli\u003eTube: Carbon Truss Tube\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TS Optics","offers":[{"title":"Default Title","offer_id":40759804854467,"sku":"GSRC14TG2","price":7237.4,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/1924\/6275\/products\/RC14ObservatoryTelescope_4.jpg?v=1632495794","url":"https:\/\/www.horizonastronomy.ie\/en-dk\/products\/copy-of-ts-optics-ritchey-chretien-f-8-14","provider":"Horizon Astronomy • Telescope Center","version":"1.0","type":"link"}
