Maksutov-Cassegrain SkyWatcher 180/2700mm telescope with EQ6-R Pro GoTo mount
Maksutov-Cassegrain catadioptric optical tubes have always stood out for their enormous contrast and magnification power. In addition, because their optical system is based on integrated mirrors, Maksutov-Cassegrain tubes are free of any kind of chromatic aberration. This makes them an ideal alternative to the classic achromatic refractors as they improve them in terms of chromaticism.
On the other hand, it is worth mentioning that the SKYWATCHER Maksutov-Cassegrain model presented here has a Maksutov corrector plate made of the highest quality glass. The result is undoubtedly a guarantee of success.
Without a doubt, the SkyWatcher EQ6-R (GOTO) equatorial mountis the jewel in SkyWatcher's crown. With unmatched reliability and robustness, the EQ6-R equatorial mount is the guarantee to start doing deep sky photography with guarantees and at the most economical price possible . The SKYWATCHER mount provides the precision and stability needed to start making observations in a more serious way.SKYWATCHER telescopes supplied with a German equatorial mount with integrated SynScan system are high quality observing platforms with well thought-out mechanics and electronics .
The main features of the GOTOsystems are summarized below:
PC operation:
SKYWATCHERSynScan mounts come standard with the revolutionary SynScan Computer Controller. Locating an astronomical object has never been so easy and fun. The telescope responds immediately to keystrokes on the control knob, executing the indicated operations. The SynScan series telescopes can also be remotely controlled from a PC using any Planetary software (Cartes du Ciel, The Sky, etc) and via RS-232 connection to the control knob. There is even the possibility to optionally purchase a GPS to facilitate the most accurate entry of time, date and location. The SynScan firmware can be upgraded via internet with a specific and free software.
Motors, crowns and bearings:
The SKYWATCHERmounts of the SynScan series use DC stepper motors with high torque capacity and microstepping control technology for maximum accuracy. Bronze crown and worm gear system for precision mechanical incremental movement to minimize gear backlash.
Tracking speeds and modes:
The versatility of the SynScan system allows various search and guidance speeds to be selected. The tracking modes are: Lunar, Solar and Sidereal. The mount is compatible with use in both the Northern and Southern hemispheres.
Database:
The SynScan computer includes a database of over 40,000 objects in memory. The library includes objects for advanced studies, following the existing catalog system: NGC, IC, Caldwell, Messier and other lists plus 25 user-definable objects (comets, asteroids, etc).
Astrophotography:
Astrophotography enthusiasts will greatly appreciate the presence of the AUTO-GUIDER port that allows autoguider functions to be performed via a PC. The SynScan firmware includes the SynScangramming algorithm for periodic error correction (this error is natural and inherent to all corona-bisenfin systems). In addition, this algorithm can be complemented with the Backlash compensation function (technical term to describe gear backlash) for both AR and DEC. In this way it ispossible to have uniform GOTO's and tracking.
