Télescope pour l'astronomie CGEM II SC 8'' EdgeHD - Celestron

The Celestron CGEM II SC 8'' EdgeHD telescope combines a motorized equatorial mount with an EdgeHD optical system to deliver high-quality images. Ideal for visual observation and astrophotography, this telescope is designed to reduce off-axis star coma and provide a flat astrographic-quality focal plane.SpecificationsAdvantagesCompatibilityIncluded ItemsOptical design: Schmidt-Cassegrain (SC)Diameter: 203 mmFocal length: 2032 mmAperture ratio: F/10Magnification: 29x to 480xLimiting stellar magnitude: 14Light-gathering power: 843xResolution power - Rayleigh: 0.69 arcsecondsResolution power - Dawes: 0.57 arcsecondsPrimary mirror type: Spherical concavePrimary mirror lock: YesPrimary mirror ventilation: ActiveSecondary mirror type: Hyperbolic convexSecondary mirror obstruction diameter: 64 mmSecondary mirror obstruction: 31%Field edge correction: HDOptical coatings: StarBright XLTFastar system compatibility: YesFocusing system: KnobEyepiece holder diameter: 31.75 mmFemale diagonal adapter diameter: 31.75 mmEyepiece 1 focal length: 40 mmEyepiece 1 magnification: 51xFinder scope: 9x50 straightOptical tube material: AluminumDovetail bar: Losmandy/CGEOptical tube dimensions: 432 x 238 mmOptical tube weight: 6350 gMount model: CGEM II - Celestron Motorized Go-To Equatorial MountLoad capacity: 18 kgRecommended astrophotography load: 12 kgLatitude adjustment range: [15; 70]°Tracking mechanism: Motorized and controlled via hand controllerMotorization: Included (Go-To)Motor type: DC servo motorsMaximum slewing speed: 4.5°/sPolar alignment: Equatorial, Northern and Southern HemispheresControl interface: NexStar+NexStar+ database: Over 40,000 objectsAlignment procedures: 2-star alignment, 1-star alignment, Solar System alignment, Last alignment, Quick alignmentCompatible software: Celestron Starry Night Special Edition Software and SkyPortal AppPolar scope compatibility: YesGPS: YesAuxiliary port(s): 2Autoguide port(s): 1Mini USB-B port(s): 1 (on the hand controller)Accessory tray: YesDovetail compatibility: Vixen/CG-5 and Losmandy/CGERequired power: 12 V; 3.2 AIncluded counterweight: 1 x 7.7 kgTripod leg material: AluminumTripod leg diameter: 50.8 mmHeight range (mount and tripod): [1346; 1651] mmTripod weight: 9000 gMount weight: 18140 gIncluded accessories: Cigarette lighter power cable C-18769Total kit weight: 41700 gEdgeHD optics for aberration-free imagesFlat astrographic-quality focal planeStarBright XLT optical coating for maximum light transmissionPrimary mirror lock for stable image acquisitionPrimary mirror ventilation to dissipate warm airFastar system compatibility for increased versatilityMotorized equatorial mount for precise celestial object trackingRobust database with over 40,000 objectsAll-Star polar alignment procedure for enhanced precisionPermanent periodic error correction (PEC)Cigarette lighter power cable C-18769
