Meade ETX-LS LightSwitch Telescope properties
The revolutionary ETX-LS telescope offers the most advanced electronics and optics ever applied to a consumer telescope. Meade aimed at an easy to use telescope that is suitable for teaching but also for high-performance applications. This telescope uses the revolutionary LightSwitch technology and Schmidt-Cassegrain optics.

What LightSwitch Technology?
Imagine that a telescope needs a point of reference every time it is set up. Normally this is done each time by aligning the telescope with Polaris (the only star on a fixed position). However, the Meade ETX-LS has an integrated sensor module which has the following properties: integrated GPS sensor, LTN module and ECLIPS (Electronically Controlled Locate Identify Position System) + built-in CCD camera

What makes this telescope so special?
This is the first telescope taking the work entirely out of your hands. In other words, this is the only telescope that we offer with a built-in camera so you can take picturesand that can find all the stars and planets on its own. You only need to indicate to the remote what you want to see and the telescope rotates automatically to the desired object. Multimedia Output

The telescope is able to find its place, time, date, position and alignment with the stars

  • Built-in professionally created multimedia tour that tells you what you see when you look through the eyepiece.
  • Built-in speaker and audio jack for additional instructions and audio descriptions of objects
  • More than 500 objects in the database with audio information
  • Video output for video presentations and images of many objects: you can connect this to an (optional) video monitor

Built-in Camera

  • Immediately start with astrophotography with the built-in CCD camera
  • Take digital photos of your favourite celestial objects and watch them directly on an (optional) video monitor or save them to an SD card
  • There is also an optional DSI CCD camera available to store such images on your computer
  • Has a built-in SD slot for updates and to store photos

AutoStar 3 + mount: automatic and built-in control

  • Operation: Select an object in the AutoStar, press "GoTo". Thereafter, the selected object will appear in your eyepiece. The hand-held computer, AutoStar III, works like professional observatories, the database contains more than 100,000 celestial objects like stars, planets, satellites, comets. With one simple operation the AutoStar controls the built-in motors, and finds these items quickly, accurately and reliably. AutoStar also gives you access to control the "Astronomers Inside multi-media" with video and audio information.
  • The tripod is very stable and is designed for larger telescopes
  • The worm gear has 4,875 drives and gives a very stable acceleration on both axes (horizontal and vertical)
  • Uses 8 "C" batteries making it available in the field as well Tip: Combine this telescope with the Meade Universal AC adapter (see bundle offer on this page), so this telescope can be simply plugged into the mains outlet
  • The manual control is well-concealed in the built-in base
  • Telescope has USB ports for other accessories
  • Heavy and stable tripod for easy movement without vibration

ACF Optics
Meade ACF optics has a huge advantage over conventional optics i.e., you have no Coma! Coma is an image error occurring with objects outside the "image centre". Stars will acquire a comet-like tail. Further information about the ACF optics can be found here The ETX-LS ACF offers a picture quality so far only achieved with a Ritchey-Chrétien costing a multiple of this ETX-LS ACF! The technique normally used by professionals, is now within your reach!

In short, this is definitely the most versatile telescope at this price

Differences between the various Meade LS Telescopes
Meade LightSwitch ETX-LS is available in three different versions:

  • Meade LS with 6 inch (150mm aperture) WITHOUT ACF optics (so not coma-free)
  • Meade LS with 6 inch (150mm aperture) WITH ACF optics (so coma-free)
  • Meade LS with 8 inch (203mm aperture) WITH ACF optics (so coma-free)

The difference is displayed in the product name (without and with ACF in the name)
