Just because a star may be millions of years old, doesn't mean it should take you that long to find it.

Until now, the stargazer's two biggest challenges to enjoying the night sky have been aligning their telescope and finding objects. Meade's new ETX Premier Edition eliminates these two challenges and makes astronomy as easy as pushing a button – right out of the box. Want to see a hard-to-find deep space galaxy? Simply push a button. The same goes for planets, stars, nebulae and more. Just pick an object you want to observe, press a button, and then AutoStar® will automatically point your telescope and put it right in your eyepiece.

Don't know what you want to see this evening? Go to the “Tonight's Best™” tour in your AutoStar. It automatically selects the best objects in the sky for that particular time and location (from its database of over 30,000 celestial objects). All you need is a clear night, a dark sky and a little curiosity. Whether you already know the sky by heart, or are just beginning your journey of discovery, your Meade ETX-Premier Edition will take you where you want to go. Astronomy has never been so fun and rewarding.

Additional Features

  • Automatic Alignment + SmartFinder™ - Meade's new ETX-Premier Edition automatically levels your telescope, points it to North and sets the time. You just enter your location or zip code. After your ETX completes its patented Level North automatic alignment procedure it will point to the first alignment star. Use the new wide-field SmartFinder to center the red dot over the alignment stars for ultra-precise pointing accuracy. It's that easy.
  • Electronic Level Sensor
  • Electronic Magnetic North Sensor
  • High Precision Internal Clock
  • Red Dot Viewfinder (SmartFinder™)
