Bosma card (BOSMA) 150/1800 3 Maka Astronomical Telescope is China's first set of independent design, independent production, with independent intellectual property rights of the top astronomical telescopes. The series in 2002 by Carl Zeiss AG of Germany and have been exported to test the United States, Germany, Italy, France, Japan, Hong Kong and other countries and regions. Since 2003, sales in the domestic market simultaneously. This series has the following seven outstanding advantages: 1, optical system uses high-performance, excellent image quality of three Maksutov - Cassegrain system, which consists of a crescent moon and two spherical mirrors refractor composed of more than ten working procedure through fine processing and coating, to ensure the quality of the optical system to achieve sharp limit. PL coupled with high-quality eyepiece, can clearly distinguish the distant universe, the two stars in close proximity. This telescope can be observed with the moon, planets, stars, clusters, comets, nebulae and other celestial bodies. Can watch daytime landscape. Optical quality, leading edge. Second, with EM11-A large high-precision intelligent equatorial satellite with automatic searching and tracking system, enabling fast automatic search, tracking all kinds of objects, arbitrary. Built-in polar axis aligned telescope user-friendly Arctic. Third, China's first all steel chrome tripod to ensure that the main tube and mounts do not occur in the course of the slightest shake fully shown steady and atmospheric qualities. Fourth, the other can be equipped with interfaces, plus optional CCD camera and the receiver, enabling real-time observation or demonstration, international general SCT configuration interface, standard 2-inch interface, can be directly supporting the international import generic diagonal mirror and other accessories. 5, cost-effective superior alternative to imported products. EM11-A equatorial mount Transmission: high worm Teeth: 180 Drive: DC servo motor deceleration Control accuracy: 10 ° Control Speed: 9 files maximum 5 ° / S Tracking Rate: Sidereal time, the sun, the moon Multi Interface: Yes Polar axis mirror: 6X20 Most polar axis height: 70 ° Load capacity: 15KG Operating Voltage: DC 12V System parameters: 32-bit CPU, fast response to commands High end, high-precision optical encoder sensing control system Periodic error correction, intelligent precision compensation Facilitate intelligent initialization, only need to enter the time and place Precise celestial coordinates compensation 21 X8 large-screen display for more information Database of more than 130,000 objects, 256 custom stars 9 stall speed adjustment Built-in clock, no need to re-start after the set interval Reliable motor overload protection Rs232 multi-interface support for PC software-driven tracking LED Backlight illumination can be used to access information
