![]() ![]() The use of 2 inch eyepieces allows the maximum possible field of view to be exploited. 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 very high-contrast optics are optimised 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 parabolic primary mirror is diffraction limited, allowing sharp images of the object. Globular clusters, such as the famous M13 cluster in Hercules, can be resolved at their edges to a large degree. With 78% more light gathering ability compared to a 150mm telescope, even the delicate spiral arms of many galaxies and additional structures in other nebulae can be observed. With a 200mm aperture, this telescope opens up new details in deep sky observing for the observer as compared to smaller telescopes.
