RADIAN EYEPIECE INSTRUCTIONS

Thank you for purchasing a Tele Vue Radian eyepiece. Each of these new 1¼"

barrel models feature 20mm of eye relief along with a 60 degree apparent field.

Using a variant of the original Nagler design, we were able to keep the size and

weight down, while achieving the best sharpness, linearity (freedom from

pincushion distortion) and ghost suppression over the entire field for any speed

(f/#) telescope.

Your new Radian eyepiece is designed for optimum viewing whether or

not you wear eyeglasses. Our unique new “Instadjust” eyeguard housing allows

for full eye relief for eyeglass wearers in the down position. Pulling the housing

up will permit click-stop setting of the eyeguard height allowing for an ideal match

between your eye and telescope pupils. With this much eye relief available, it

is important to learn your own optimum “click stop” position.

If you don’t wear eyeglasses, start with the eyeguard housing pulled out all

the way. You can fold the soft rubber eyeguard up or down, whichever is most

comfortable for you. You may not see the full field with the eyeguard housing fully

extended; just keep “clicking down” until you find the most comfortable position

where you still see the entire field (this is much easier to do than to explain how,

thank goodness). You will also find that this system minimizes extraneous outside

light, giving you the highest contrast for those “faint fuzzies”. The generous

20mm of eye relief also minimizes eye lens fogging due to eye moisture in cold

weather. See reverse side for operation with pupil guide.

Following is a table of all Radian focal lengths and their corresponding

effective field stop diameters. To determine the true field in degrees for an

eyepiece on any given telescope, simply divide the field stop diameter of the

eyepiece by the focal length of the telescope (in mm) and multiply the

result by 57.3 degrees (a radian).

Warning: to avoid getting dust and dirt into the eyepiece, do

not unscrew the chrome barrel.
