Visit Sky-Watcher Skymax 200DX is a telescope Maksutov-Cassegrain aplanétique designed for astrophotographers and visual observers who are looking for the ultimate top-level optics, able to offer a great sharpnessa high contrast and a perfectly flat field, even with large, modern sensors.
With its 200 mm openinghis 2000 mm focal length and its f/10 focal ratio, this optical tube is a particularly interesting solution for the’lunar and planetary observation, but also for the’high-resolution astrophotography on compact deep-sky targets.
The Skymax 200DX is equipped with a specific optical design which effectively removes off-axis coma. The result is a optimized, totally flat field of vision, with remarkable homogeneity from the center to the edge of the field.
Thanks to a 44 mm image circle, this model allows aberration-free imaging over the entire useful surface, to meet the needs of users wishing to operate large-format cameras, including in configurations full frame. This native ability to cover a large corrected field makes the Skymax 200DX a particularly attractive lens for modern astrophotographic workflows.
With its 200 mm effective opening, the Skymax 200DX collects enough light to reveal many fine details, while its 2000 mm long focal length naturally favors high magnifications and sampling adapted to high-resolution cameras.
He excels in the study of the Moonand planets and their fine structures, while remaining highly relevant for imaging compact deep-sky objects such as certain planetary nebulae, globular clusters or galaxies of small apparent size.
The great 44 mm image diameter is one of the major assets of this lens. Where many instruments are more limited in coverage, the Skymax 200DX is clearly aimed at users wishing to work with larger large, modern sensors without any major compromise on field quality.
For those looking for a brighter instrument with a wider field of view, a optional 0.7x reducer/corrector is available separately as reference 20118. It allows the telescope to be upgraded to a faster configuration at f/7, offering even greater imaging versatility.
The Skymax 200DX features a 12 V cooling fan as well as a ventilated primary mirror cell. This design helps the tube reach the’thermal equilibrium, This is essential if we are to exploit the full potential of a 200 mm telescope, especially for planetary observation and high-resolution imaging.
Faster warm-up helps to limit internal turbulence and preserve the finesse of the details observed or recorded.
The Skymax 200DX is equipped with a 70 mm diameter secondary mirror, with a 94 mm total central obstruction baffle included, i.e. 22 % per surface. This configuration helps keep the contrast and the return of fine details.
The tube also receives a new Zero Shift focusing system, designed for greater ease of use and reduced image displacement during focusing. The focus button integrates a patented focus distance indicator, covering a range from 38 m to infinity.
Compact for its class, well-balanced and designed for serious use, the Skymax 200DX provides an excellent base for a fixed observatory installation or for a transportable imaging setup, provided it is combined with a equatorial mount adapted to its load.
The tube is supplied with a 75 mm dovetail and two supports for researchers already assembled. It is important to note, however, that the Skymax 200DX OTA is supplied without accessories..
