Celestron 31057 Omni 150 XLT Reflector Telescope
A great telescope for beginners, the Celestron 31057 Omni 150 XLT Reflector Telescope thrills astronomy enthusiasts by bringing faint deep space objects into sharp view. It possesses a powerful light gathering capacity that exceeds the keenest dark-adapted vision by 459 times, bringing to light wonders which otherwise escape the naked eye.
The Omni XLT 150 frees images from the chromatic aberrations typical of achromatic refractors. With Newtonian reflector optics and an f/5 parabolic mirror that uses aspheric shaping technology in crisp, sharp relief, minus any spherical aberrations. It has a 6” aperture, 750mm focal length, and an aluminium optical tube which allows the reflectors to quickly cool to ambient temperatures.
Each Omni XLT is hand-selected for the highest grade reflectors and lenses. Light transmission is optimized with StarBright XLT coatings. Each telescope includes a 25mm multi-coated eyepiece, a 1.25” star diagonal, and a 1.25 rack and pinion focuser.

For the price one could do no better than the Celestron 31057 Omni 150 XLT Reflector Telescope. The Omni 150 outclasses its 130-150 competitors with ease. The large 150 reflector collects great amounts of light, resulting in everything from the moon, Saturn's rings, Jupiter and its moons, as well as deep space objects like nebulae and constellations.
A great scope for beginning astronomers, they will soon feel like pros once they feel the heavy, precision control of the mount, and its motorized clock drive, which allows objects to be tracked from sunset to sunrise. They will soon be tracking objects they didn't know were there before.
The first thing you notice is how heavy this telescope actually is. Enthusiasts might prefer to keep it set up in a permanent spot. However if you wish to take it out, you'll find the ease of set-up and the durability of its materials to be more than up to the task for all kinds of weather and terrain conditions. This makes scouting new sites with better visibility a fun and rewarding experience this telescope offers.
Because it's a reflective telescope, images appear reversed and upside down. In order to use it for terrestrial viewing you'll have to purchase a additional erecting prism for image correction. For more detail-oriented intermediate and expert users, the use of additional eyepieces may bring other planets into sharper detail.
The Celestron 31057 Omni 150 XLT Reflector Telescope combines high quality optics and light-touch mechanics with great performance and ease of use, in a very stable, yet portable package. With high attention to manufacture quality and detail, and convenient expandability, this telescope packs a lot of big bang for the buck; it will provide years of stimulating activity for the growing astronomer.
