The optical path and components of the ETX telescope design
Designed in the USA.
The Meade ETX90 GoTo telescope features an advanced Maksutov-Cassegrain design for pinpoint star images and extraordinary contrast. This makes it fantastic for brighter deep sky objects and ideal for detailed lunar and planetary observation as it easily soars to high magnification. The 90mm (3.5") telescope aperture has a focal length of 1250mm, f/13.8, and includes Meade's best Ultra-High Transmission Coatings (UHTC). Use your smartphone or other dedicated astrophotography camera to take high quality solar system images including the rings of Saturn, cloud bands of Jupiter, and extremely high resolution details of the lunar surface.
The Meade AudioStar features audio files and an internal speaker.
With the included AudioStar telescope hand controller you have easy access to thousands of objects along with a wealth of data about each one! AudioStar Astronomer Inside technology features a built-in speaker that plays over four hours of educational content about the celestial objects you are viewing! After a very simple alignment routine, the AudioStar is ready to take you to any object above the horizon in its database. Can also be connected to a PC for more advanced control.
The Audiostar telescope hand controller database includes over 30,000 objects that you can view with a simple press of a button! AudioStar Astronomer Inside technology features a built-in speaker that plays over four hours of educational content about the celestial objects you are viewing! This computerized celestial object locating system plugs into the telescope's handbox port allowing for a quick and easy telescope alignment. Once aligned with the sky, the AudioStar is ready to take you to any object above the horizon in its database. In addition to GoTo and tracking capability, the AudioStar permits a wide array of fascinating and educational functions such as multiple Guided Tours, digital positional readouts, the ability to link the telescope with a PC using Meade's #505 connecting cable, and much more.
Standard equipment includes a Meade 884 telescope field tripod, Meade 26mm Series 4000 1.25" Super Plössl eyepiece (48X), Red-dot Finder, Smart Phone Adapter, Moon Filter, and Moon Map. The very stable tripod features chrome plated tubular steel legs and for the astrophotographer conveniently has a built-in wedge which can be used for polar alignment of the telescope. The ETX telescope is internally powered by 8 (user-supplied) AA batteries which will run it for approximately 20 hours under normal usage. An AC adapter is also available for separate purchase.
The similarly advanced telescope optical tube design incorporates a unique flip mirror mechanism, allowing light to either go to the comfortable 90 degree observing position of the eyepiece or the built-in camera attachment port at the rear of the telescope tube. Optional adapters are available for many popular camera models.
The ETX telescope optical tube and motorized fork assembly weighs a mere 7 lbs. making the Meade ETX90 a world class performer in a very portable package.
