When attached to any of the following long eye relief Tele
Vue eyepieces, DIOPTRX compensates for your eyesight
astigmatism. Most of these eyepieces have long eye relief
for eyeglass wearers, so simply adding DIOPTRX toreplace your eyeglasses should leave you with comfortable
eye relief. DIOPTRX corrects astigmatism only, since
focusing compensates for your power correction.

Pull off and save rubber eyeguard from eyepiece.
While holding lower engraved bottom ring of DIOPTRX with one hand, unscrew upper top ring (containing lens and rubber eyeguard) just enough so the assembly slips over the eyepiece top.
While still holding the lower ring, re-tighten upper ring on DIOPTRX so it locks onto the eyepiece, then loosen it slightly so DIOPTRX is free to rotate. (Note: you can leave it
locked onto Radian and Nagler Type 4 eyepieces because rotation can be done using their “Instadjust” housing.)
Place the chart on the reverse of this page at a distance so you can view it through your telescope, using your DIOPTRX equipped eyepiece (or use an actual star field). Focus at
the center of the field and rotate DIOPTRX to optimize the astigmatism correction for the sharpest image you’ve ever seen. DIOPTRX is most effective with large exit pupils. Hint
for setting rotation: view a star slightly out of focus, and simply rotate DIOPTRX until star disc appears circular then focus normally.
Keep the lens cap on, and clean as necessary, just as you would clean any other multi-coated optical glass surface.
