Would you like to have an eyepiece that acts like a whole collection of eyepieces?
How about a telescope eyepiece or spotting scope eyepiece that has a wide variety of magnifications – yet you never have to switch them out?
Then take a look at the Everwin 7-21mm Premium Zoom Eyepiece!
The Everwin Zoom Telescope Eyepiece is like having several eyepieces rolled into one. Just rotate the body and change the magnification – with a range from 7mm to 21mm and everywhere in between! It fits in a standard 1.25″ focuser and is threaded to accept filters.
The Everwin Zoom Eyepiece has multi-coated optics for clear, bright images that have plenty of contrast and good colour correction. It has a 30 to 40 degree apparent field of view and an excellent 16mm to 33mm eye relief – depending on what magnification factor you select.
The Everwin Zoom Eyepiece also works great in spotting scopes, too!
