The return of the extremely popular ETX125 takes mobile astronomy to the next level. This large 127mm aperture and 1900mm (f/15) focal length marry the portability of the ETX with Meade’s premium optics. The ETX125 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. The ETX125 Observer also includes a stable but portable full-size steel tripod with dual-fork mount and equatorial (EQ) tilt plate - allowing for polar alignment, which is ideal for astrophotography. This model has an internal 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 sold separately. The ETX125 Observer also comes with a bubble level/compass to help with leveling the tripod and mount. Approximate assembled weight: 25 lbs.

The ETX Observer Series features Ultra-High Transmission Coatings (UHTC™). UHTC™ gives maximum light transmission, ensuring the brightest images and the highest contrast. Enjoy detailed, close-up views of the Moon and planets, and be amazed by the stunning views of star clusters, nebulae, and more!

The ETX Observer Series also features a fully-equipped, GoTo system with AudioStar™. In addition to finding and tracking objects in the night sky, AudioStar™ also boasts a number of features of its own, including: 30,000+ object-database, built-in speaker, and over 4 hours of audio content that educates you about objects you observe.

Whether you’re observing on the go or from your backyard, the ETX125 Observer will make exploring the night sky easy, educational, and exciting. Go ahead, start exploring!
