How to Choose Eyepieces for Any Telescope

Scott Roberts from Explore Scientific takes you step-by-step on how to choose a good selection of eyepieces for any optical telescope that accepts interchangeable eyepieces that you own. 

Scott covers how to select lowest useful magnification by determining your eye's fully dilated pupil size, and highest useful magnification for the aperture of your telescope and by determining the seeing conditions of the sky. He also discusses intermediate magnifications. Most points that anyone would consider in choosing eyepiece are covered, including: focal length, apparent field of view, true field of view, eye relief, and contrast. 

Although we highlight Explore Scientific eyepieces, the methods described in this video work for any brand or type of eyepieces that you may be considering. 

 

Observing the sky since his childhood, Scott W. Roberts is the Founder of Explore Scientific and is an avid observer. He loves space exploration, nebulae, spiral galaxies, and travelling to star parties with his Airstream. You can follow Scott on facebook @ScottInSpace.
