The Eye Piece, a collection of stacked polished glass cut and arranged in such a way to compliment the Optical Tube Assembly that one attaches it to. The Eye Piece to some of us can be just as an obsession as the OTA. I can easily become addicted to the these “little jewels”. I am somewhat selective but economic as well. Below is my modest list.
Magnification Formula is below.
Magnification = Objective Focal Length/Eyepiece Focal Length
Example: A 1600 mm focal length telescope using a 10 mm eyepiece will produce a magnification of 160 X’s:
Example: Magnification = 1600 mm/10 mm = 160x
The Addition of a Barlow Lens in the optical path will Multiply that magnification by 2. Thereby reducing the need to purchase additional eyepieces. So if you already own a 20mm eyepiece and you add a Barlow you will also have a 10mm eyepiece, with some loss in resolution, however, very little depending on the quality of the Barlow and Eyepiece combination.
