This astrophotography optimized apochromatic refractor consists of four elements in three groups : 2-1-1 configuration. This unique design of FPL-53 (Ohara) fluorite glass illuminates 45mm diagonal color-coded sensors with dot-shaped star images - perfect for full-frame cameras!

The 1:10 reduction and 35 mm focus 2.5 "pull-out is M48-threaded for a wide range of camera connectivity options, such as the M48 threaded bayonet adapter that directly attaches a DSLR Since the correction optics are already integrated into the optical system of the Star 71, there are no problems with the optical path lengths, which one usually has when using an external flattener.

The Apochromat Star 71 is ideal for photographing large areas of fog , such as rosette or lagoon (M8), as well as large galaxies such as Andromeda (M31) or triangular (M33) galaxies.

The Star 71 was developed for photography. Therefore, it is not delivered with a zenith mirror. It can also be connected to a normal 2 "-Zenitspiegel, as the back focus of the Star 71 is not enough.To make the Star 71 but can also be used visually, William Optics has developed a special zenith mirror on which as usual 1.25" -Okular can be inserted. You will find the mirror under "Recommended Accessories".
