The Basics of Telescope Eyepieces

A basic overview of eyepieces for beginner telescopes. I cover the eyepieces that come with many beginner telescopes, details on the different types of eyepieces, and general ideas about upgrading and buying new eyepieces.

Some of the eyepieces I discuss in this video:

Almost the Bob Ross of telescopes. Very informative and calm. The right amount of information at the right pace.

Great video, helped me with exactly what I was looking for. Thank you.

Very well done. Just as a side note, I use a 55mm-2” eyepiece for a very wide field of view. A similar wide field can be obtained from a 40mm-1 1/4” eyepiece. Wide fields mean any planets will look small with very little detail, but extended objects like galaxies and wide nebulae will fill your field of view in dark skies. My choices for focal length are 55mm, 40mm, 24mm, and 16mm.

This is outstanding!!! My father ground his own mirrors & fabricated all of his telescopes, which I used as a kid. I grew up loving to look at the stars.

But now, I only have a small Meade scope, with eyepieces that I got from a friend. I had no idea how use those - now I do! Thanks greatly for your video!!
