Great video!
If this gets enough views, you could make a video on binoculars, too. They are super fascinating as well.

Randy, your channel has immense potential. even with the small amount of subscribers and views, you are producing excellent videos with at least the same quality of larger channels like VSauce. keep it up! I love your work.

I looked up Abberation in the dictionary and couldn’t find it, cause turns out it’s spelled Aberration haha. Minor mistake though, still a great video! Thanks

Why do refracting telescopes require more upkeep than reflecting ones? I’ve been interested in getting a telescope recently, so this video was really helpful, but I was kind of confused on that part.
