The Fish-Eye lens MAO-08 is intended for observations of weak extended objects (aurora, twilight and dawn phenomena, stratospheric clouds, etc.) in narrow spectral bands with variable passband filters VARISPEC and in white light.

Besides having high power this lens can be used for meteor observations. It has been tested during the winter field conditions.
