Now even the casual
telescope user can enjoy the benefits of zoom eyepiece technology. A twist of
this affordable 7-21mm 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! Actual
magnification range will depend on the focal length of your telescope. It works
equally well for astronomical or terrestrial viewing. This four-lens telescope
eyepiece boasts fully coated optics and exceptionally long eye relief ranging
from 33mm to 16mm. Apparent field of view is 30-deg at 21mm and 43-deg at 7mm.
Rubber traction ring ensures a good grip. The 1.25" barrel is threaded for
filters. A nice value in a quality zoom eyepiece!
