Amateur Astronomy Video 4 - Eyepieces, Focal Length, Magnification
About | Information | History | Online | Facts | Discovery
This is my 4th video in my series about Dobsonian Mount telescopes. It is all about understanding eyepieces and their relation to the telescope. Learn how to determine the magnification of an eyepiece with your telescope and how to choose new eyepieces.

Question....
Doesn't aperture create field of view?
If you have an eye piece with 100o field, it won't matter if your aperture only opens to 60o field..... -
Awesome video. I need that eyepiece...but 350.00 damn

Great video! Have you ever looked at building a telescope?
-
I love that 17mm you got. Great for my Mead ETX-125 and Zhumell 12"

Good video Benjamin!!! Forgot to mention that you really don't get the total of FOV that comes (AOFV) with your eyepiece because you still have to divide the AFOV in the magnification and then get the true field of view (TFOV)

This video was extremely helpful. It made a somewhat difficult topic seem concise and easy. Keep up the great work!
