Remarks:

A beast!! Over 6kg, it requires a solid mount and tripod of the sort used for small telescopes. With its 110mm objective lenses, it provides a wonderfully bright image and great displays of the moon, Jupiter and its moons, or Saturn. This model is sold in almost identical versions under several different brands; unfortunately, it is only available in non-ED glass versions, so it displays a bit of chromatic aberration; precise eye placement behind the eyepieces is advised to reduce the effect as much as possible.
