Astro Tutorial #1.5: Focal Length and Aperture V2 - enhanced audio

-- Version 2.0: enhanced audio quality -- Hey folks, in this video we cover the defining properties of a scope. We will discuss: Focal length and Aperture and what other properties derive from those two. So what should a scope claim to catch your attention? Why shouldn’t you buy a “300x magnification scope” for 20$? ;) We will find answers to that and talk about optical resolution the field of view or the light gathering capabilities of scopes. And then, if you are used to all of this terms, you can start to decide what scope might fit you best. Clear skies and till next time! Greetings Chris Hashtags: #focal_length #aperture #FOV
