The ETX 90 Observer fully equips the modern explorer with a sophisticated, automated and portable telescope. Its dual-purpose design includes a removable OTA and includes exceptional features like AudioStar, GOTO technology, and large 30,000 object database. Its a perfect scope to accompany you during camping, hiking, and outdoor activities. Exploring and night-sky stargazing is made fun, easy and educational. With the ETX 90, youll see planets, stars, galaxies and nebulae at the push of a button. The legacy of the ETX Series continues.
The ETX90 Observer has a Maksutov-Cassegrain optical design for pinpoint star images and extraordinary contrast, making it a great deep sky performer and ideal for detailed lunar and planetary observation at high magnifications. The Ultra-High Transmission Coatings (UHTC) give maximum light transmission, ensuring the brightest images and the highest contrast. It has a flip mirror included to let light focus to the rear of the telescope (instead of the mirror reflecting the light 90 degrees to the eyepiece), allowing attachment of a camera on the back of the scope (adapters not included). The ETX90 Observer comes with a bubble Level/Compass to make sure your tripod and mount are level.
