With a 200 mm aperture, this telescope opens up new details in deep sky observing for the observer as compared to smaller telescopes. With 78% more light gathering ability compared to a 150 mm telescope, even the delicate spiral arms of many galaxies and additional structures in other nebulae can be observed. Globular clusters, such as the famous M13 cluster in Hercules, can be resolved at their edges to a large degree. The parabolic primary mirror is diffraction limited, allowing sharp images of the object. The very high-contrast optics are optimized by the use of a small secondary mirror and thin secondary mirror spider vanes, allowing sharp and bright planetary observing even at higher magnification.
The OTA has a solid 2-inch Crayford focuser for a low image shift focusing - of particular importance at high magnifications and for astrophotography. The use of 2-inch eyepieces allows the maximum possible field of view to be exploited. The telescope has an f5 aperture ratio, putting it in the class of 'fast' Newtonian telescopes, so this telescope is particularly well suited to astrophotography. The 9 x 50 finder scope is highly useful as you can already see objects due to the large aperture that is not even visible to the naked eye. The OTA is also visually a real gem, featuring an elegant design for the both OTA and finder scope in an aesthetically pleasing shimmering black.
