Telescope magnification power with a 30 mm eyepiece for a telescope?
The magnification of a telescope is given by dividing the Telescope’s focal length by the focal length of the eyepiece. For example, if you had a telescope with a 900mm focal length and used a 30mm eyepiece, the magnification would be 30 power (30x).
How do you calculate magnification given the focal length of a telescope and eyepiece?
Focal length of Telescope divided by focal length of eyepiece, using the same units of distance.
Telescope eyepiece which is better?
It’s time for a 2 inch eyepiece and i’m stuck between two.
The 30 mm GSO Super-Wide
Or the 32 mm Q70 from Orion.
Which would u prefer?
They are actually made by the same company. GSO is Guan Sheng Optical of Taiwan, one of the largest manufactures of optical devices in the world. They contract out to anyone who wants their services.

For a modest fee and a certain minimum purchase quantity, you can even have them personalize the eyepiece instead of theirs or Orion’s. A buddy of mine did that for our astronomy club.
So, go with the lowest price you can find.
