With telescopes from the StarSense Explorer series you will easily find the best observation objects in the sky - with no need for a star chart!
Simply insert your smartphone into the special telescope holder, launch the free StarSense Explorer app, and the app will guide you to planets, double stars, the Orion Nebula, the Andromeda Galaxy and other fascinating objects.
A very important factor in evaluating the performance of telescopes is transmission, that is the proportion of incident light that arrives at the image plane.
The main characteristics of the StarBright®-XLT coating are as follows:
The entire optical system consisting the corrector plate, mirror and lenses achieve a transmission maximum of 89% at 520 nanometres (where the dark-adjusted human eye has its highest light sensitivity). The average transmission over the entire visual spectrum from 400 to 750 nanometres is 83.5%.
