With it, you can see details on the Moon\u2019s surface, the phases of Venus, the polar ice caps on Mars, Jupiter\u2019s four moons and Saturn\u2019s rings. Take a look at our other <a href=\"https:\/\/www.fotomonza.com\/tuote-osasto\/kiikarit-ja-kaukoputket\/tahtikaukoputket-kiikarit-ja-kaukoputket\/\">astronomical telescopes in our range<\/a>.<\/p>\n<h4>Alignment without a star chart<\/h4>\n<p>With Celestron\u2019s patented SkyAlign alignment system, you enter the date, time and location into the hand controller and then point the telescope at any three bright celestial objects. You don\u2019t need to know the names of the stars, as the Moon and bright planets can also be used as alignment points.<\/p>\n<h4>Power supply and hand-held controller<\/h4>\n<p>The telescope is powered by eight AA batteries or a separately available mains adaptor (#18778). The internal battery compartment supplies power to the precision servo motors, and the cable from an external battery pack cannot become tangled around the mount. The ergonomic hand controller can be removed from its holder or left in place; it is used to select the object list, adjust the rotation speed, read information about objects and check whether the desired object is visible in the sky.<\/p>\n<h2>Main features<\/h2>\n<ul>\n<li>The GoTo control system moves the telescope to the object selected from the hand controller\u2019s object list.<\/li>\n<li>This ready-assembled, adjustable stainless steel stand can be set up in minutes without the need for tools.<\/li>\n<li>The quick-release fork arm and tube make assembly and disassembly quick and easy.<\/li>\n<li>The long focal length of Maksutov-Cassegrain optics brings out the fine details of the planets and the Moon.<\/li>\n<li>Servo motors ensure that movements remain smooth and vibration-free during observation.<\/li>\n<li>Battery operation makes it possible to carry out observations even in places where mains power is not available.<\/li>\n<\/ul>\n<h2>Technical specifications<\/h2>\n<ul>\n<li>Telescope type: Maksutov-Cassegrain<\/li>\n<li>Lens diameter: 90 mm<\/li>\n<li>Focal length: 1250 mm<\/li>\n<li>Optical coating: FC (fully coated)<\/li>\n<li>Guidance: computer-controlled GoTo<\/li>\n<li>Power supply: 8 \u00d7 AA batteries (not included) or mains adaptor #18778 (optional)<\/li>\n<\/ul>\n<p>View all <a href=\"https:\/\/www.fotomonza.com\/tuotemerkki\/celestron\/\">Celestron products<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"<p>The Celestron NexStar SLT 90 Mak is a computer-controlled GoTo telescope featuring 90 mm Maksutov-Cassegrain optics and a focal length of 1,250 mm.
