Ce moteur RA facile à installer compense la rotation de la Terre, de sorte que le télescope suit le mouvement d'une étoile dans le ciel nocturne d'est en ouest. Lorsque la monture du télescope est correctement alignée polaire et que le lecteur RA est fixé et en marche, l'utilisateur n'a qu'à faire des ajustements occasionnels de la déclinaison (Dec) pour garder un objet dans l'oculaire pendant de longues périodes. L'entraînement par moteur à axe unique Celestron fonctionne sur une pile 9 V, il n'y a donc pas de câbles gênants. Le lecteur peut être utilisé dans l'hémisphère nord ou sud. Pour changer d'hémisphères (inverser le sens du moteur), il suffit de basculer l'interrupteur N\/S sur la face du moteur. Il est également simple de modifier la vitesse du moteur. Un bouton \"Speed ​​Rate Regulator\" est situé juste sous l'indicateur d'alimentation et peut être tourné dans les deux sens pour ralentir ou accélérer le moteur. Étant donné que les objets du système solaire comme la Lune et les planètes se déplacent dans le ciel à des vitesses différentes de celles du ciel profond font, cela vous donne la possibilité d'adapter la vitesse du moteur au type particulier d'objet que vous observez. \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"\/\/cdn.shopify.com\/s\/files\/1\/1935\/4371\/files\/astromaster_130_90_motordrive_large.gif?v=1505422267\" alt=\"\" style=\"display: block; margin-left: auto; margin-right: auto;\"\u003e\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eLogiciel de nuit étoilée\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e Téléchargez le logiciel Starry Night de Celestron et découvrez le ciel nocturne, les objets célestes et comment planifier votre prochaine session d'observation.

Astrograph\u003c\/h2\u003e\n\u003cp\u003eThe Askar N160 f\/3.6 Newtonian combines a 160mm parabolic primary mirror with an included 0.95x triplet coma corrector to create an exceptionally fast f\/3.4, 544mm focal length imaging system. Weighing just 3.97kg, the carbon fiber optical tube is optimized for deep-sky astrophotography with APS-C format sensors, delivering a 0.73\" theoretical resolution. The integrated corrector provides a standard 55mm back focus from its M48x0.75 threads, simplifying camera and accessory integration for capturing wide-field targets.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eFast f\/3.4 Imaging: 160mm Aperture with a 0.95x Corrector\u003c\/h3\u003e\n\u003cp\u003eThe optical system is built for speed and light-gathering power. The 160mm primary mirror collects significant signal, while the f\/3.4 corrected focal ratio allows you to capture faint details in nebulae and galaxies with shorter sub-exposure times. This reduces demands on your mount's tracking accuracy and allows more data to be collected in a single session.\u003c\/p\u003e\n\u003cp\u003eThe included 0.95x triplet corrector is essential for a fast Newtonian, sharpening stars across the APS-C (28mm) image circle and preventing the characteristic comatic aberration that affects parabolic mirrors. With the corrector, the focal length is a wide-field 544mm, perfect for framing large targets like the North American Nebula (NGC 7000) or the Andromeda Galaxy (M31).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eCarbon Fiber Tube: A 3.97kg OTA for Thermal Stability\u003c\/h3\u003e\n\u003cp\u003eConstructed from carbon fiber, the optical tube offers superior thermal stability compared to aluminum.

With an optical tube weighing just 11 lbs 14.3 oz and a base at 19 lbs 6 oz, this telescope is a portable and powerful instrument for backyard astronomy.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e154mm f\/7.6 Optics: Resolving Power for Planets and Deep Sky\u003c\/h3\u003e\n\u003cp\u003eThe 154mm parabolic primary mirror is the core of this telescope, gathering enough light to resolve details that are invisible to smaller scopes. You can clearly see the cloud bands of Jupiter, the rings of Saturn, and the phases of Venus. The 1170mm focal length and moderate f\/7.6 ratio create a versatile system that excels at both planetary and deep-sky observation without requiring exotic, expensive eyepieces to produce sharp stars edge-to-edge.\u003c\/p\u003e\n\u003cp\u003eThis optical design is also excellent for breaking up brighter deep-sky objects. You can resolve individual stars in the Hercules Cluster (M13) and trace the faint dust lanes of the Orion Nebula (M42).

You get two eyepieces, a 25mm for wide-field views and a 10mm for higher-power (50x) looks at the Moon and planets. A red-dot finder makes it simple to aim the telescope at your target.\u003c\/p\u003e\n\u003cp\u003eTo help you navigate the cosmos, the kit comes with a smartphone mount and access to an AR-Telescope App. By mounting your phone to the telescope, the app uses your location to display an augmented-reality view of the sky, helping you identify constellations and locate objects you want to observe.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eNewtonian EQ vs. Tabletop Dobsonian: Choosing Your First 114mm Telescope\u003c\/h3\u003e\n\u003cp\u003eA common alternative to this telescope is a 114mm tabletop Dobsonian.

However, it requires constant nudging in two directions to keep objects centered.\u003c\/p\u003e\n\u003cp\u003eThis telescope's Equatorial (EQ3) mount is its defining advantage. The ability to track a planet with one simple motion is a significant step up, especially for beginners who want to study details without the object drifting out of view.

For deep-sky objects, it will reveal bright star clusters like the Pleiades (M45), nebulae like the Orion Nebula (M42), and the core of the Andromeda Galaxy (M31).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eIs the equatorial mount on this 114mm Newtonian difficult to set up?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eAn equatorial mount requires an initial \"polar alignment\" step that a simpler alt-azimuth mount does not. However, for visual observation, this alignment can be done quickly by pointing the mount's axis roughly towards Polaris (the North Star). The major benefit is that once aligned, you only need to turn one knob to track objects as they move across the sky.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow does the AR-Telescope App work with this 114mm reflector?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe included smartphone mount attaches your phone to the telescope.

Assembly is a dedicated imaging instrument, combining a fast 200mm f\/3.8 primary mirror with a 4-lens ED corrector to produce a 45mm flat image circle. Its 760mm focal length frames large deep-sky targets, while the carbon fibre sandwich tube construction maintains focus stability at a low weight of approximately 6kg. With tight stellar spot sizes of just 4.1µm on-axis and 8.1µm at the edge of the field, the AG8 delivers sharp, coma-free stars across full-frame sensors.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eFast f\/3.8 Optics: The 200mm Primary and 4-Lens Corrector\u003c\/h3\u003e\n\u003cp\u003eThe AG8 is built for speed. The 200mm primary mirror operates at a native f\/3.8, drastically reducing exposure times compared to f\/5 or f\/6 systems and allowing you to capture more data in a single night. This aggressive focal ratio is managed by an integrated 4-lens ED corrector, which eliminates off-axis coma and produces a flat field, ensuring that stars remain pinpoint across the entire frame.\u003c\/p\u003e\n\u003cp\u003eThe 90mm secondary mirror provides even illumination over the 45mm image circle, a necessary design choice for a fast, wide-field astrograph. While this large central obstruction compromises some contrast for high-resolution planetary viewing, it is an essential trade-off for achieving the bright, wide-field performance required for deep-sky imaging.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eAstrograph Engineering: Carbon Fibre Tube and 3\" Ceres Focuser\u003c\/h3\u003e\n\u003cp\u003eAn imaging platform must be mechanically rigid and thermally stable. The AG8's tube is constructed from a carbon fibre sandwich material, which has a near-zero coefficient of thermal expansion.

AG14 Optical Tube Assembly combines a massive 350mm primary mirror with an incredibly fast f\/3.8 focal ratio to dramatically reduce exposure times on faint deep-sky objects. Its integrated 4-lens ED corrector delivers a flat field larger than 50mm, producing sharp stars with spot sizes as small as 3.4µm on-axis and 4.7µm at the field edge. This 1330mm focal length astrograph is engineered for the largest modern sensors, providing professional-grade results from a precision-built instrument.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003ef\/3.8 Corrected Newtonian Optics: A \u0026gt;50mm Flat Field\u003c\/h3\u003e\n      \u003cp\u003eThe AG14's optical system is designed for one purpose: wide-field imaging. The fast f\/3.8 primary mirror gathers immense amounts of light, while the custom-designed 4-lens ED corrector eliminates coma and field curvature. This results in a corrected image circle greater than 50mm, fully illuminating full-frame and larger format astronomy cameras without vignetting or distorted stars at the edge of the frame.\u003c\/p\u003e\n      \u003cp\u003eWith measured spot sizes of just 3.4µm on-axis and 4.7µm at the field edge, the AG14 delivers resolution capable of matching the smallest pixels on modern CMOS sensors.

This material offers exceptional rigidity at a manageable weight of approximately 24kg and, more importantly, exhibits near-zero thermal expansion. As temperatures drop during an imaging session, the 1203mm tube length remains constant, preventing focus shift that can ruin long exposures.\u003c\/p\u003e\n      \u003cp\u003eThe 350mm primary mirror is held securely by a CNC-machined aluminum 9-point suspension cell, which provides uniform support to prevent gravitational flexure as the telescope tracks across the sky. For rapid thermal stabilization, the mirror cell is equipped with three controllable fans to bring the primary mirror to ambient temperature quickly, minimizing tube currents and ensuring sharp images from the start of your session.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003e3\" Ceres Focuser with 79mm Back Focus\u003c\/h3\u003e\n      \u003cp\u003eThe AG14 comes standard with a robust 3\" Ceres rack and pinion focuser, designed to handle the weight of large cameras and heavy accessory stacks without slipping or tilting.

observatory-class imaging instrument built around a hand-figured, 400mm f\/4 primary mirror guaranteed to a 1\/10 PV wavefront accuracy. Paired with a thermally inert carbon fiber sandwich tube and a 9-point flotation cell, its 1600mm focal length is engineered to deliver maximum resolution and contrast on the most demanding deep-sky and planetary targets. Weighing approximately 36kg, the CT16 OTA combines massive light-gathering power with the optical precision required for serious astrophotography.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e1\/10 PV Wavefront Optics: The Foundation of CT16's Imaging Power\u003c\/h3\u003e\n\u003cp\u003eThe heart of the CT16 is its Suprax primary mirror, finished to Orion Optics UK's highest \"Ultra\" grade of 1\/10 PV wavefront. This isn't an optional upgrade; it's the standard for the entire CT line, ensuring that the optical system delivers virtually perfect images. Each mirror's performance is verified by a Zygo laser interferometer, and a report is supplied with the telescope, providing absolute confidence in its quality.\u003c\/p\u003e\n\u003cp\u003eThis level of precision means that the maximum and minimum deviation from a perfect parabolic wavefront is incredibly small. The result is exceptionally high contrast that resolves subtle details in galactic dust lanes and fine banding on gas giants, free from the image degradation caused by lower-quality optics.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eCarbon Fiber Tube \u0026amp; 9-Point Cell: Engineering for Stability\u003c\/h3\u003e\n\u003cp\u003eAt an aggressive f\/4 focal ratio, maintaining precise focus is critical. The CT16's tube is a sandwich-construction carbon fiber design with a 450mm diameter, providing extreme rigidity and near-zero thermal expansion. This ensures the 1600mm focal plane remains locked in place as temperatures change, eliminating a common source of image drift during long imaging sessions.\u003c\/p\u003e\n\u003cp\u003eThe 400mm primary mirror is supported by a CNC machined, 9-point suspension cell that prevents gravitational flexure as the telescope tracks across the sky. An integrated fan system provides active cooling, allowing the massive mirror to reach thermal equilibrium quickly for stable, sharp views from the start of your session.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e400mm Aperture at f\/4: A Deep-Sky Imaging Powerhouse\u003c\/h3\u003e\n\u003cp\u003eWith a 400mm (16\") aperture, the CT16 gathers an immense amount of light, making it ideal for capturing faint nebulae and distant galaxies. The fast f\/4 focal ratio allows you to collect significant signal in shorter sub-exposure times, reducing demands on your mount's tracking and minimizing noise. This combination of light grasp and speed makes the CT16 a formidable tool for advanced deep-sky imaging.\u003c\/p\u003e\n\u003cp\u003eThe optical path includes a 90mm secondary mirror held by a fully adjustable, stainless steel 4-vane spider.

This allows for critical focusing accuracy, essential for extracting the maximum detail the 1\/10 PV optics can deliver. The focuser has the back-focus and load-bearing capacity to handle modern imaging trains, including filter wheels and off-axis guiders.\u003c\/p\u003e\n\u003cp\u003eFor initial alignment and target acquisition, a high-quality 8x50 achromatic finder scope is included.

On a target like Jupiter, a 1\/4 PV system might show the main equatorial belts clearly, but the 1\/10 PV optic will resolve finer, low-contrast details within those belts, along with delicate festoons and small ovals that would otherwise be smeared out.\u003c\/p\u003e\n\u003cp\u003eFor deep-sky objects, this translates to superior stellar resolution. When viewing the Hercules Cluster (M13), a 1\/10 PV mirror will produce tighter, more point-like stars across the field, allowing you to resolve individual stars deeper into the cluster's dense core. This is the practical benefit of minimizing wavefront error: more light is focused into the central point of a star's image, increasing sharpness and contrast on every object you view.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat kind of mount is required for the Orion Optics UK CT16 OTA?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe CT16 optical tube weighs approximately \u003cstrong\u003e36kg\u003c\/strong\u003e and the rings add another \u003cstrong\u003e3.5kg\u003c\/strong\u003e, for a total weight of nearly 40kg before adding any imaging equipment.

This process, called thermal equalization, minimizes \"tube currents\"—internal air turbulence that can soften the image—leading to sharper, more stable views.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ctable class=\"DAV-specifications\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptics Grade\u003c\/td\u003e\n\u003ctd\u003e1\/6 PV Wavefront Standard (Upgrades to 1\/8 PV \u0026amp; 1\/10 PV available)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Mirror Diameter\u003c\/td\u003e\n\u003ctd\u003e200mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocal Length\u003c\/td\u003e\n\u003ctd\u003e900mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocal Ratio\u003c\/td\u003e\n\u003ctd\u003ef\/4.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSecondary Mirror Size\u003c\/td\u003e\n\u003ctd\u003e63mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocuser\u003c\/td\u003e\n\u003ctd\u003eEris 2\" Rack and Pinion with smooth lock\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMirror Cell\u003c\/td\u003e\n\u003ctd\u003eCNC 9-point suspension\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMirror Cooling\u003c\/td\u003e\n\u003ctd\u003e12-volt fan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTube Material\u003c\/td\u003e\n\u003ctd\u003eAluminium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTube Weight\u003c\/td\u003e\n\u003ctd\u003e7kg (nominal)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTube Diameter\u003c\/td\u003e\n\u003ctd\u003e225mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTube Length\u003c\/td\u003e\n\u003ctd\u003e860mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTube Finish\u003c\/td\u003e\n\u003ctd\u003eGalaxy Silver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cul class=\"DAV-grid\"\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/davidastro.com\/pages\/orion-optics-uk-warranty-policy\" rel=\"noopener\" target=\"_blank\"\u003eOrion Optics UK 1-Year Warranty\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Orion Optics UK","offers":[{"title":"Professional (1\/6 PV)","offer_id":52942596899101,"sku":"OOUK-IDEAL-8","price":1707.0,"currency_code":"CAD","in_stock":true},{"title":"Research (1\/8 PV)","offer_id":52942596931869,"sku":"OOUK-IDEAL-8-1-8-PV","price":1822.0,"currency_code":"CAD","in_stock":true},{"title":"Ultra (1\/10 PV)","offer_id":52942596964637,"sku":"OOUK-IDEAL-8-1-10-PV","price":1843.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/5280\/1565\/files\/OrionOpticsUK-IDEAL-8-Optical-Tube-Assembly-1_b4c117bd-1387-4576-935c-b3beedbbe56a.jpg?v=1789608219"}],"url":"https:\/\/davidastro.com\/fr\/collections\/reflectors.oembed?page=3","provider":"David Astro","version":"1.0","type":"link"}
