This generous aperture allows you to partially resolve globular clusters and brings distant galaxies and nebulae into clear view under dark skies. If you are observing near city lights, adding a nebula filter helps to cut through urban light pollution.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe telescope utilizes a standard 1.25\" connection, making it compatible with any standard 31.7mm astronomical eyepiece. Additionally, its integrated standard SC thread opens up a world of customization. You can upgrade to enjoy wide-field 2\" eyepieces, or attach a Celestron T-adapter to connect SLR cameras and binocular viewers for versatile astrophotography and viewing.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eThe Mount:\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003eThe SLT mount is a single-arm alt azimuth mount and is optimized for quick setup and easy portability. Unlike a traditional equatorial mount, you don't need to painstakingly align the telescope to the north, adjust the polar altitude, or carry counterweights. The mount is simply set up horizontally, and after alignment (which involves simply selecting any three bright stars), the computer automatically ensures that the telescope slews to the desired objects and keeps them in focus: The automatic tracking compensates for the Earth's rotation. This makes SLT telescopes ideal for anyone who wants to observe the night sky firsthand: Quick to set up and with all the necessary convenience.\u003c\/p\u003e\n\u003cp\u003eHowever, this doesn't mean you have to forgo astrophotography: Lunar photography with a DSLR or planetary photography with a video camera like the Celestron NexImage 5 are also possible with the SLT altazimuth mount. A T2 thread is integrated into the 1.25\" reducer. However please note that for deepspace astrophotography an equatorial mount is recommended\u003c\/p\u003e\n\u003cp\u003eThe hand controller contains a database with thousands of objects to view. These include, of course, the planets of the solar system, as well as countless galaxies, nebulae, star clusters, and interesting stars. Having trouble choosing?\u003c\/p\u003e\n\u003cp\u003eSkyAlign - Setup without prior knowledge of the sky:\u003c\/p\u003e\n\u003cp\u003eThe NexStar SLT mount has motors with encoders on both axes and to initialize the computer control, simply enter the time and location (selectable from the database) into the hand controller and slew to any three bright celestial objects – it doesn't matter which ones, you don't even need to know them! Once the alignment is correctly done, the mount then knows what the sky looks like above it and will automatically point to any other object at the touch of a button.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"text-decoration: underline;\"\u003eTip\u003c\/span\u003e: The SLT telescopes can be retrofitted at any time with the optional StarSense module – then the initialization of the telescope runs fully automatically! This is a small camera that mounts to the telescope, allowing it to automatically orient itself in the sky – without GPS. With StarSense, all you have to do is set up the telescope, turn it on, and wait about three minutes. Since StarSense is compatible with all modern, computer-controlled Celestron telescopes, you can continue using it even if you later upgrade to a larger telescope – StarSense also works with observatory-class telescopes.\u003c\/p\u003e\n\u003cp\u003eLike all Celestron NexStar telescopes, the NexStar SLT can also be controlled via PC. All you need is the USB cable. Using the NexRemote software or the widely used ASCOM interface, you can then control the telescope from a Windows PC.\u003c\/p\u003e\n\u003cp\u003eThe battery compartment is integrated into the mount and hidden under a cover. This eliminates the need for an external battery pack to become a tripping hazard.\u003c\/p\u003e\n\u003cp\u003eThe Celestron NexStar SLT telescope mount is a robust single-arm altazimuth mount that can be assembled without tools. Large, easy-grip screws make assembly possible even with gloves. The sturdy steel tripod features a storage tray for accessories and a holder for the hand controller and the mount supports telescopes weighing up to approximately 4kg, depending on the design. The clamping mechanism on the mount's arm is compatible with any standard Vixen (V) dovetail joint and holds it securely. A bubble level integrated into one of the tripod legs also simplifies setup and helps you level the mount before use.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"text-decoration: underline;\"\u003eThe Power Supply\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe computer control system naturally requires power. The mount offers several power supply options: either via eight standard AA batteries for complete independence, or via an optional car cigarette lighter adapter cable, or via an optional AC adapter. The integrated battery compartment in the mount eliminates cable clutter and allows for maximum portability.\u003c\/p\u003e\n\u003cp\u003eSpecifically designed for Celestron telescopes, a separate outdoor Power Supply which is is cold-resistant is also available. It delivers the necessary voltage even at low temperatures – cheaper power supplies designed for indoor use often provide insufficient power in cold conditions.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cspan style=\"text-decoration: underline;\"\u003eNote:\u003c\/span\u003e Please make sure the correct power supply is used to prevent damage to the sensitive electronics.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecs:\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOptical Design: Schmidt Cassegrain\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eAperture: 150mm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFocal Length: 1500mm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eF Ratio: f\/10\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMount: Alt Azimuth\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eControl: USB Hand controller\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePower Supply: Batteries (Not included) or a separate power supply\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDovetail: Vixen\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTracking modes: Azimuthal, EQ-North, EQ-South\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTracking Speeds: Sidereal, Lunar \u0026amp; Solar\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eGoto: Yes\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDatabase: 40,000 objects\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eAlignment methods: SkyAlign + Auto 2-Star Align, 1-Star Align, 2-Star Align, Solar System Align\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTripod: Stainless steel\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eWeight: 9kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eWhats included:\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cem\u003e150mm Schmidt Cassegrain telescope \u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eSLT mount + NexStar hand controller \u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003e1.25\" zenith prism\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003e25mm and 9mm eyepieces\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eStarPointer red dot finder\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cem\u003eAstronomy software download\u003c\/em\u003e\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Celestron","offers":[{"title":"Default Title","offer_id":58875546960207,"sku":"821771","price":1024.19,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/1924\/6275\/files\/Celestron-150SC-SLT-Astronomy-Telescope-for-Beginners_9.webp?v=1790272010","url":"https:\/\/www.horizonastronomy.ie\/en-it\/products\/celestron-nexstar-slt-6-schmidt-cassegrain","provider":"Horizon Astronomy • Telescope Center","version":"1.0","type":"link"}
