The Sky-Watcher Horizong 90 (or 90/900 AZ3) scope is optically identical to the Luna 90 astronomical telescope but has been optimized for daytime used (the azimuthal mount and an Amici prism is included). The scope provides very good image quality but can be used even at high magnifications between 100-150x and provides rich and detailed images. During nighttime the Moon and planets can be also observed and gives nice views of the brighter deep sky objects as well. A 10mm and 25mm Barium eyepiece is included, resulting in 36x and 90x magnifications.

The T2 mount makes it possible to attach any DSLR camera with a proper bayonette adaptor making it a 900mm telephoto lens.
