Meade ETX-90 Portable Observatory


 The fully go-to computerized ETX-90 Portable Observatory is designed to be the ideal ultra-portable telescope. It combines Meade’s unsurpassed optics with industry-leading electronics to deliver a truly exceptional viewing experience. The computer-optimized Maksutov-Cassegrain optics of the ETX-90 yield remarkable lunar, planetary, star cluster, and binary star images. Thanks to the cost efficiency of modern injection-molded components, these images cost far less than those of apochromatic refractors and competitive fork-mount Maksutovs of similar aperture.
The ETX-90’s standard equipment AutoStar computer hand control is amazingly simple to operate. It will even help you align the scope on the sky. You don't have to know Castor from Pollux, or Albireo from Zubeneschamali. All you have to do is tell the AutoStar where and when you are on Earth, level the tube, and show it where North is located. The AutoStar computer will do the rest.
