However, you will see vignetting when using DSLR cameras. This comes from the body of the camera or from the adaption via the M48 adapter. By using flats, you can eliminate this vignetting. Full-frame CCD cameras are not affected by it, as the distance to the sensor is bigger and the cameras usually have a larger connection thread.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpec:\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAperture: 358 mm \/ 14\"\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFocal ratio (without corrector): f\/4.5\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eEffective focal ratio: f\/5.1 (due to the extension factor of the corrector)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFocal length: 1837mm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePrimary mirror: Mirror substrate Pyrex, conical\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSecondary mirror: Diameter 104mm minor axis\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTube: Diameter 412mm - Wall thickness 11mm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePrimary mirror cell: fully adjustable primary mirror cell\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e* \u003cem\u003eAs this is a Special Order Telescope for specialised Astrophotography, please contact us for more detailed information if needed prior to purchase.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eWhats included:\u003c\/em\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli style=\"font-style: italic;\"\u003e\n\u003cem\u003e14\" Optical tube assembly\u003c\/em\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli style=\"font-style: italic;\"\u003e\n\u003cem\u003eCNC tube rings\u003c\/em\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli style=\"font-style: italic;\"\u003e\n\u003cem\u003e8x50 finder, straight view\u003c\/em\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli style=\"font-style: italic;\"\u003e\n\u003cem\u003eDust cap for the front side\u003c\/em\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli style=\"font-style: italic;\"\u003e\n\u003cem\u003e3\" Newtonian focuser with reduction to 2\" and 1.25\"\u003c\/em\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli style=\"font-style: italic;\"\u003e\n\u003cem\u003eN-AGK3 corrector\u003c\/em\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli style=\"font-style: italic;\"\u003e\n\u003cem\u003eVIP-3010-M68 - M68 connection\u003c\/em\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli style=\"font-style: italic;\"\u003e\u003cem\u003eCollimation manual and manufacturing protocol\u003c\/em\u003e\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"TS Optics","offers":[{"title":"Default Title","offer_id":54680918458703,"sku":"N-AG14","price":7763.02,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/1924\/6275\/files\/TS_NGA14_14_Newtonian_Telescope_7.jpg?v=1742239753","url":"https:\/\/www.horizonastronomy.ie\/en-gr\/products\/ts-optics-ng-14","provider":"Horizon Astronomy • Telescope Center","version":"1.0","type":"link"}
