Remarks:

A typical example of the high power astronomy and nature observation binoculars coming out of Chinese production lately. This type of instrument has been constantly improved over the last few years, and is being generically sold under different brand names and with different materials for the outside of the body, as well as with different qualities of coatings. The Lunt represents the upper end version of this binocular, but still features non-ED glass (for the ED glass version, see the APM 20×70 ED APO in this collection, https://binocular.ch/apm-ms-20×70-ed/). The Lunt brand has been discontinued recently, and instruments under the APM brand have taken their place.
