A twist of the affordable 7-21mm Orion Explorer II Zoom Telescope Eyepiece housing changes the focal length from 21mm to 7mm, or to any focal length in between. That makes it ideal for locating an object at low magnification, then zooming in at higher magnifications for closer inspection. Without changing eyepieces!
