The ETX series is a portable, simple, and fully automatic telescope.

Starting your astronomy journey with the BCTO ETX-90BB is an excellent choice. Take advantage of 3.5"of aperture to enjoy close-up views of the solar system and celestial objects anytime, anywhere. Packing your ETX-90BB Observer and tripod at a moment’s notice is a breeze with the carrying case and durable tripod bag.

The ETX-90BB telescope fully equips the modern explorer with a sophisticated, automated and portable telescope. The Handset controller includes GOTO technology, and a large 30,000 object database. With the ETX-90BB, you'll see planets, stars, galaxies and nebulae at the push of a button.

The ETX-90BB 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 multi-coating offer maximum light transmission, ensuring the brightest images and the highest contrast. It has a flip mirror 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 ETX-90BB also comes with a Bubble Level/Compass to make sure your tripod and mount are level.

A portable but extremely stable full size steel tripod is included in this wonderful telescope package, and it is topped with an equatorial tilt plate, allowing for the polar alignment necessary for long exposure astrophotography. You will also receive a hard carry case for the mount/optical tube and accessories, and a tripod bag for the tripod. This super portable, super powerful telescope is ready to go at a moment’s notice, a cinch to set up, and a blast to use!
