You can achieve up to 25% shorter exposure times and sharper imaging than, for example, through a comparable Schmidt-Cassegrain telescope. For the use of a reflex camera without focal length reduction you need the 50mm and the 25mm extension between focuser and telescope.\u003c\/p\u003e\n\u003cp\u003eThe generous backfocus also allows the connection of correctors (which we recommend for the use of full-frame sensors).

When the temperature changes slowly during an exposure, other mirror substrates, like Pyrex, tend to a deformation of the mirror and thus to a shift of the focus. This problem does not exist for mirrors of quartz glass. Therefore the focus is better maintained which is very important for long exposures. Both mirrors are coated with 94% reflectivity material which means the image is obviously brighter than many other designs with only 90% reflection.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe advantages of TS Ritchey-Chrétien telescopes for Astrophotography:\u003c\/strong\u003e\u003cbr\u003eThe TS RC astrographs are true Ritchey-Chrétien telescopes. 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. RC telescopes have hyperbolical primary and secondary mirrors. They are more difficult to manufacture, but offer a significantly sharper field with less aberrations throughout the field.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat makes the Ritchey-Chrétien Telescope superior to Schmidt-Cassegrain telescopes for Astrophotography:\u003c\/strong\u003e\u003cbr\u003eSchmidt-Cassegrains generally require a corrector 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":"celestron-sc-xlt-8-optical-tube","title":"Celestron SC-XLT - 8\" (Optical Tube)","description":"\u003cp\u003eCelestron's C8 Schmidt-Cassegrain telescopes have been impressive for decades and owe their good reputation to the combination of excellent optics with a compact, lightweight design.

In photographic images, no spikes can be seen on the stars, which were otherwise produced by the spacer plates.

However, the new SD series is also optimised for use with full-frame cameras through the use of new inner baffle rings. The large 60mm eyepiece extension also allows heavy cameras to be attached without tilting. Furthermore, the included diagonal mirror allows comfortable observation even in difficult observation positions and additionally offers a T2 thread for connecting a DSLR camera.
