The STS 65 is a lightweight and handy spotting scope that offers high optical quality despite its compact dimensions. The straight view of the STS 80 is particularly beneficial to those who need to find moving targets quickly.
Objective lens diameterThe objective lens diameter specifies how much light can enter the optics. This makes it a key factor in an instrument’s performance, for example, in twilight. The bigger the objective lens diameter, the more light the objective lens can capture. The darker the surroundings, the larger the objective lens diameter needs to be. Check the precise product name as the number after the ‘x’ specifies the objective lens diameter in millimeters. For example, a device with the suffix 10x42 has an objective lens with a diameter of 42 mm.
