A " quick" reflector telescope on the German EQ4 equatorial mount. With the supplied eyepieces and Barlow lens, it can produce magnifications of 32, 64, and 128x. The focal length of this telescope is 800 mm and the diameter of the main mirror is 203 mm (8 inches): these parameters give the instrument a large aperture ratio.
The resolving power of this telescope is about 0.6 kt/s and the permeability is 14oV. This is sufficient to comfortably observe not only Messier objects, but also fainter astronomical objects such as faint planetary nebulae, spiral galaxies, etc.
Dual-axis fine-motion mounts provide accurate and smooth guidance of objects as they move across the sky. Although the reflector tube has a large wind resistance, with careful balancing of the balance weight, the tube will stand firmly on the metal tripod.
Due to its open construction, the SIGETA ME-200 reflector easily withstands temperature fluctuations and is virtually fog-free inside, unlike most refractor models.
The telescope's class is indicated by its integrated pole finder for easy installation of the polar axis. One of the viewfinder lenses features a diagram of the position of the stars in the vicinity of Polaris. WARNING: the axis setting technique should not be neglected - particularly if you plan to take photographs or work with a short-focus eyepiece.
Fast newtons, such as the ME-200, are better suited to 'portrait' astrophotography. If panoramic shooting is the user's goal, auxiliary comma correction accessories will be needed. A 4mm wide-angle eyepiece may be recommended as an accessory. (Further reductions in eyepiece focal length will increase the formal magnification of the instrument, but will not actually be useful due to a significant reduction in image quality).
