- version 2.0 : enhanced audio and no coffee - Hey folks, this time we want to open up the telescopes to look what’s inside. We will discover different types of telescopes – some with lenses, some with mirrors or even some with both of it. What is an apochromatic Refractor? How does a Newtonian Reflector work? Lets find out! Clear skies everyone and have fun! Greetings Chris Hashtags: #mirror_telescope #lens_telescope #types_of_telescopes
