Achromatic refractor with objective diameter 70 mm and focal length 900 mm.

.
This lenticular telescope collects 98x more light from the human eye at night. It is mounted on an azimuthal mount, and the whole thing is light enough to easily move to other locations, such as away from artificial light sources that have an adverse effect on night sky observations. The image seen is bright and high-contrast.
