Celestron NexStar 5 SLT Telescope
It's Advanced Schmidt Cassegrain Design provides a powerful telescope in a compact package, and it is combined here with Celestron’s user friendly Nexstar GoTo system. This makes it a very attractive package for beginners and experienced astronomers alike.
You can expect to see pleasing levels of detail on Solar system objects, and in particular some lovely lunar detail. Brighter deep sky objects will also be visible such as the Andromeda galaxy, M13 globular cluster, The ring nebula and more, but it must be noted that fainter objects are also very dependant on the quality of your sky. Please do not hesitate to ask us for advice.
How to align a Celestron Computerised Telescope
Celestron’s innovative NexStar Star Location Telescope (SLT) has been a customer favorite for years thanks to its unique combination of high quality optics, user-friendly computerized interface and a sturdy single fork arm mount.
This telescope comes with a preassembled, adjustable stainless steel tripod, quick release fork arm, NexStar+ computerized hand control, 5” Schmidt-Cassegrain optical tube, and lots of bonus accessories.
The entire telescope kit weighs in at just 16 pounds. The simple, no-tool assembly and fast SkyAlign alignment procedure will have you ready to observe in minutes. This makes NexStar 5SLT your perfect companion for impromptu observing sessions and all-night stargazing marathons alike.
Your NexStar 5SLT will reveal details of the lunar surface, Venus and its phases, the polar caps on Mars, Jupiter and its four moons, and Saturn with its rings plainly visible. It can also be used as a land-based spotting telescope for daytime and wildlife observations.
Schmidt-Cassegrain Optical Tube
The NexStar 5SLT comes with a 5” Schmidt-Cassegrain optical tube, a great multi-use telescope with 1250 mm of focal length (f/10). The Celestron C5 is equipped with patented StarBright XLT coatings, which visibly increase contrast and bring out subtle detail on the Moon, planets, and faint nebulae. These coatings also increase light transmission for brighter deep space images.
The Celestron C5 strikes an excellent balance between portability, ease of use, light gathering ability and price.
The Mount & Technologies
Computerized Alt-Azimuth telescope – The NexStar SLT telescope features a single fork arm alt-azimuth mount, which allows the telescope to track the desired objects as they appear to move across the night sky. The mount sits on a pre-assembled, adjustable steel tripod.
NexStar+ Hand Control – This computerized hand control enables you to automatically slew to any of 4,000+ celestial objects with the push of a button. The NexStar+ database includes more than 600 galaxies, 300 clusters and dozens of beautiful binary stars. Not sure what to observe? Choose the Sky Tour feature and the NexStar+ hand control will automatically generate a list of all the best celestial objects currently visible based on your exact time and location.
SkyAlign Technology – Our proprietary SkyAlign alignment procedure makes setting up and using a computerized telescope faster and easier than ever before. Point the telescope at three bright objects in the sky, and the telescope can triangulate its position and locate any other object in the sky automatically. You don’t need to know the names of the stars—you can even pick the Moon or bright planets! For more information about our SkyAlign technology, visit here.
Power – Go anywhere! Feel free to enjoy your NexStar SLT in remote dark sky locations—it’s powered by 8 AA batteries (not included) or a PowerTank portable battery. The internal battery compartment provides power to the high precision servo motors for rigid low-vibration performance while eliminating cord wrap issues associated with external battery packs. You may also charge your telescope with a 12V AC adapter (sold separately).
Your telescope includes a StarPointer red dot finderscope, a star diagonal, and two eyepieces (20mm and 9mm). The two eyepieces offer different magnifications for low or high powered observing. The star diagonal provides a right-side-up view and a more comfortable viewing angle when looking up at the sky. The StarPointer finderscope will help you quickly center an object in your eyepiece for easier observing.
NexStar 5SLT is ready to grow with you as you become a more experienced amateur astronomer. It’s compatible with all Celestron’s latest accessories, including StarSense AutoAlign, SkyPortal WiFi module, and PowerTank Lithium Pro.
