Meade LX 90 12 "telescope

The Meade LX 90 12 "(300mm) and f / 10 telescope incorporates the highest quality in the Schmid-Cassegrain optical system on the market, with a band of advanced comma-free ACF optics and, on the other hand , ultra high transmission coatings .Comma-free optics allows to widen the entire field of vision without having aberrations and not lose any detail of any celestial body, also reduces astigmatism and eliminates diffraction peaks. High quality coatings allow you to obtain the maximum brightness and contrast of The image The large aperture of this telescope is also a guarantee of much greater luminosity , a key variable in deep sky observation and astrophotography.

It is a computerized telescope of the GOTO system, incorporating the AutoAling automatic alignment system that works together with the GPS (Sony GPS reciver), which incorporates the same telescope. The AutoStar command works as a telescope control system, correcting the periodic error during trackings or routes. Finally, the AudioStar system is an audio program that informs the user of the object they are viewing, the information is given in different languages, including Spanish. It contains a library of 30,000 objects .
Sturdy aluminum double-wishbone fork with an adjustable quick turn speed of 1 to 7 degrees per second. The 8 x 50 search engine will make it easier for you to find objects in the deep sky.
