Maksutovs and Schmidt-Cassegrains have spherical mirrors and need correctors for making a large field usable. With Schmidt-Cassegrains, you can see the aberrations in the field even when working visually. Most times, Maksutov-Cassegrains are so slow that they are not suitable for astrophotography.

Additionally, these telescopes have a Schmidt plate at the front side which is prone to dew. The RC is a pure reflection system without lenses in the light path. Thus you can use the complete light even in the infrared range. The image is brighter and the exposure times get shorter. The field of an RC telescope is coma-free by design and relatively flat.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNo shifting problem with TS RC telescopes:\u003c\/strong\u003e\u003cbr\u003eTelescopes with focusing via a movable primary mirror often suffer from mirror shifting problems. The image shifts while focusing or even jumps. TS Ritchey-Chrétien telescopes do not have this problem, as their primary mirror is fixed. Focusing is done via a high-quality focuser. An additional advantage is the optimal distance from primary to secondary mirror which gives you the guarantee of the best possible image if the primary mirror moves relative to the secondary, you will almost never have the optimal distance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTelescope Spec:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOptical Design: True Ritchey-Chrétien with a hyperbolic primary and secondary mirror.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eAperture: 6\" \/ 154mm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFocal Length: 1370mm (918mm using the \u003ca href=\"https:\/\/www.horizonastronomy.ie\/en-de\/products\/ts-optics-x0-67-ccd47-reducer?_pos=1\u0026amp;_sid=5e6823e7c\u0026amp;_ss=r\" target=\"_blank\" rel=\"noopener\"\u003eCCD47 Reducer\u003c\/a\u003e)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFocal Ratio: f\/9 (f\/5.96 using the \u003ca href=\"https:\/\/www.horizonastronomy.ie\/en-de\/products\/ts-optics-x0-67-ccd47-reducer?_pos=1\u0026amp;_sid=5e6823e7c\u0026amp;_ss=r\" target=\"_blank\" rel=\"noopener\"\u003eCCD47 reducer\u003c\/a\u003e)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eResolution: 0.76\"\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eReflectivity: 94% reflectivity non-tarnishing mirror coatings\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eBack Focus: 159mm from 2\" connection of the focuser\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTube Diameter: 191mm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTube Length: 500mm with focuser\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTube Weight: 5.4kg\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eObstruction by secondary: 77mm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFocuser: 2\" dual speed Crayford focuser\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eConnecting Thread: M90x1\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDovetail Bar: 1x GP style\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eWhat's included:\u003c\/em\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e6\" f\/9 RC Astrograph\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e2\" Crayford focuser with 1.25\" adaptor\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eVixen style dovetail bar\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eM90 Extension rings 1x 50mm and 2x 25mm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDust cover\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003c!----\u003e","brand":"TS Optics","offers":[{"title":"Default Title","offer_id":49342516527439,"sku":"TSRC6M","price":639.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/1924\/6275\/files\/TS-RC6-Telescope_1.jpg?v=1721502409"},{"product_id":"ts-optics-8","title":"TS-Optics UNC f\/6 Newtonian - 8\"","description":"\u003cp\u003e\u003cstrong\u003eThe TS Optics UNC Newtonian series offers an alternative to Newtonians made in the far east.

For standard correctors like the Baader MPCC or the TS-Optics MAXFIELD corrector we recommend the 20mm spacer, which goes between the focuser. This gives you 60mm backfocus.
