This refractor provides powerful optics and high resolution for detailed planetary observing. With its 150mm aperture, this achromatic refractor is one of the larger members of this type of telescope. With a focal ratio of f8, the most chromatic aberration is already well corrected. Of course, as a refractor, it provides especially good contrast, which is highly positive for planetary observing. Planet observing, in particular, depends on being able to see individual details, such as the polar ice caps on Mars or the Great Red Spot on Jupiter. There is nothing standing in the way of a quick trip through the solar system! Many DSOs, such as the Ring Nebula or the distant globular cluster M13 are also easily visible. Collecting 460 times more light, it shows objects that are not even to be guessed at with the naked eye alone. This instrument has a 2" focuser and includes a 1.25" reducing adapter, allowing it to be used with both sizes of the eyepiece. Using a 2" eyepiece gives you the widest field of view. So a 2" 40mm eyepiece with a 72° apparent field of view for example, will show you 2.8 degrees of sky. Extended DSOs fit well into this field of view. The 9x50 finder scope is mounted parallel to the telescope OTA and facilitates location of astronomical objects. Astrophotography can also be carried out with this telescope. The Moon, planets, and even most nebulae can be photographed with this system.
