Celestron NexStar 127 SLT Maksutov Telescope

NexStar SLT - Goto computer control for everyone!

With these telescopes you can find any celestial object of your choice immediately and without prior knowledge! Planets, comets, galaxies, comets - all at the touch of a button. A huge range of observable celestial objects is available to you, and the computer will automatically suggest what can be observed at any given moment.

The ready-to-use tripod and the quick-release couplings for connecting to the fork mount and for the optical tube on the fork head allow you to set up the telescope in just a few minutes - without any tools! All you have to do is extend the tripod to a comfortable height, screw the mount to the tripod, secure the telescope using the quick-release coupling on the dovetail bar and insert an eyepiece - that's it.

The NexStar SLT 127 - The powerful planet hunter
**

The largest Maksutov of the NexStar family is still very compact and delivers 250x magnification without any problems - Maksutov telescopes are not considered planetary specialists for nothing. This means that you are already approaching the magnification range that our atmosphere allows on average on most nights. The higher magnification of larger (and heavier) telescopes can only rarely be used. Thanks to the large focal length, you can easily reach the high magnifications required for planetary observation.

127mm aperture also allows the telescope to collect enough light to show you many deep-sky objects. Whether you're chasing double stars, gas nebulae or galaxies, the SLT127 puts them within reach, and the telescope is compact enough to easily transport to a location with dark skies and good observing conditions.

The most important figures:

OPENING: 127mm
FIRM WIDTH: 1500mm
OKULAR 1: 25mm - 60x magnification
OKULAR 2: 9mm - 167x magnification
MAXIMUM Magnification: 300x
WEIGHT: 8.2 kg

Ideal for visual observers

The SLT mount is a single-arm azimuthal mount. It is optimized to be quickly ready for use and easy to transport. Unlike the classic equatorial mount, you do not need to align the telescope to the north, set the pole height or carry counterweights. The mount is simply set up horizontally, and after alignment (in which any three bright stars are simply set), the computer automatically ensures that the telescope moves to the desired objects and keeps them in the eyepiece: Automatic tracking independently compensates for the Earth's rotation

, making SLT telescopes ideal for anyone who wants to observe the night sky for themselves: Quickly ready for use and with all the convenience you need

, but that doesn't mean you have to give up photography: Lunar photography with an SLR camera or planetary photography with a video camera such as the Celestron NexImage 5 are also possible with the azimuthal SLT mount. A T2 thread is integrated into the 1.25" reducer. You can also photograph directly through the eyepiece with a MicroStage camera platform

, but you will need a separate equatorial mount for photographing deep-sky objects, as this is the only way to achieve the necessary long exposure times. Thanks to the standardized dovetail clamp, you can attach your telescope to a suitable mount with quick coupling according to Celestron or Vixen standard at any time.

Extensive star catalogs and TOUR function for an overview

The hand controller contains a database with over 4,000 objects. These naturally include the planets of the solar system as well as countless galaxies, gas nebulae, star clusters and interesting stars. Finding it difficult to choose? Then use the TOUR mode, which shows you a selection of the most beautiful objects every evening and explains them in German on the display.

SkyAlign - set up without knowledge of the sky.

The NexStar SLT mount has motors with encoders in both axes and a hand controller with 4,000 objects in the database. To initialize the computer control, all you have to do is enter the time and location (selectable from the database) into the hand controller and move to any three bright celestial objects - it doesn't matter which ones, you don't even have to know them! Now the mount knows what the sky above it looks like and moves to any other object at the touch of a button.

Upgradeable for the latest technology - high value retention

If the SkyAlign is still too complicated for you, you can expand the telescope at any time. With the optional Celestron SkySync GPS module saves you having to enter the date, time and observation location. This data is automatically taken over by the telescope via the GPS satellites

. Would you like it to be even more convenient? The SLT telescopes are compatible with the StarSense module. This is a small camera that is mounted on the telescope and allows the telescope to orient itself fully automatically to the sky - without GPS. With StarSense, all you have to do is set up the telescope, switch it on and wait about three minutes. Since StarSense is compatible with all modern, computer-controlled Celestron telescopes, you can also continue to use it if you ever buy a larger telescope - StarSense also works with observatory-class telescopes.

This means that a NexStar SLT telescope can be brought up to date at any time if there are technical innovations - this ensures that your telescope retains its value!

Control via PC and smartphone

Like all Celestron NexStar telescopes, the NexStar SLT can also be controlled via PC. All you need is the USB cable. You can then control the telescope from a Windows PC using the NexRemote software or the widely used ASCOM interface.

But the SLT telescopes also support wireless control! Using the optional SkyPortal WLAN adapter, you can control the telescope wirelessly - either via a Windows PC or via smartphone/tablet (with the optional SkyPortal planetarium program for iOS and Android). So you don't have to take a laptop with you on your observation nights, an iPhone is all you need and you have a modern graphical telescope controller in addition to the hand controller, whose large buttons can also be operated with thick gloves. All options are open to you!

Sophisticated mount

The mount of the Celestron NexStar SLT telescopes is a solid azimuthal single-arm mount that can be set up without tools. Thanks to the large, easy-grip screws, this is also possible with gloves. The sturdy steel tripod has a shelf for accessories and a holder for the hand control box. The SLT mount supports devices weighing up to approx. 4 kg, depending on the design. This allows, for example, lens telescopes up to approx. 10 cm aperture or reflector telescopes up to approx. 13 cm aperture to be mounted stably. The clamping device on the arm of the mount fits any standardized Vixen (V) dovetail and holds it securely

. A circular bubble level, which is integrated into a tripod leg, makes it easier to set up.

Compatible with almost all astronomical accessories

The NexStar SLT 127 Mak offers the standard 1.25" connection used in astronomy. This means that all standard astronomical 1.25" eyepieces (31.7 mm) can be used. This is particularly convenient with the Baader Planetarium Q-Turret eyepiece turret, for example, which covers all useful magnifications and allows you to switch quickly between different magnifications

. With an optional adapter to T2, you can also use the telescope as a telephoto lens with a focal length of 1500mm. In order to position it precisely despite the high magnification, you can switch off the automatic tracking and still move the mount using the manual control - at high speed or at minimum speed.

Future-proof

The NexStar-SLT mount can not only be used with the telescope supplied, but also with many other telescopes or spotting scopes thanks to the standard prism clamp. Thanks to the hand controller, which can be updated via the Internet, you can always keep the software up to date and upgrade to the latest technologies such as SkyQ Link or StarSense at any time via the AUX connection. The telescope can also be used on many other mounts via the standardized dovetail bar, for example if you want to do deep-sky photography one day. A computer-controlled Celestron telescope offers everything you need to get started right away - while keeping all your options open for the future.
