Nightforce 1-4, my eyepiece focus is all out of whack, does anyone remember how to reset it? I remember someone at NF told me once you turn it all the ways clockwise and then like 3 full turns counter... anyone have any insight?

Rifle Scopes Reset Nightforce Eye Adjustment

I recently had to redo the focus of a NXS 2.5-10x32 and called NF customer service. I was told that at the factory, they use an optical tool to set diopter focus (i.e. factory standard) to +/-2 on the diopter scale. Rather than try to find factory setting without an optical tool, the best way to focus an out of whack reticle is to do the following...
NF diopter adjustment:
Mark the eyepiece (I used a small piece of tape) so you have a reference point
Break eyepiece loose and run lock-ring and eyepiece full-forward (count the # of turns so you know where you started)
Set magnification to maximum
Use a white piece of paper (or white wall)...distance does not matter, but 15 or 20 feet from wall is better
Aim at white paper (stabilizing with bipod or rest will make easier)
Look at through scope; focus on reticle (should be very blurry) for no more than 2-seconds
Do 1-full rotation outward at a time and observe using no more than 2-second looks – repeat until reticle starts looking better
Once reticle starts to look better, go to half-turn, then quarter-turn, until good
<ensure no more than 2-second looks>
I successfully performed the above procedure this past week and my reticle is now focused.

From the manual for NXS Compact:
Focusing the Reticle
The reticle focus is used for setting the reticle focus to match your particular vision. It should not be used to try to focus for parallax. NXS™ 1-4x and 2.510x32 Compact riflescopes do not have adjustable parallax; the 2.5-10 x 42 does. If you plan to wear vision correction when shooting, then set this focus while wearing your corrective lenses. Record the number of turns you have made on the eyepiece from the original factory setting so you can return to it if needed. Note: All Nightforce riflescopes are factory set for average eye strength, so this adjustment may not be necessary. 1. Set the power zoom ring at the highest magnification. 2. Look through the riflescope eyepiece at a light colored background such as a white wall, overcast sky, or drape a thin white cloth over the objective to eliminate background clutter. Determine if the reticle is clear and in focus instantly when you look through the eyepiece. Be aware that staring at the reticle for more than two seconds during this process will cause your
eye to compensate, resulting in a false indication of reticle focus. Look away for a few seconds then retry for best results. You are looking for a sharp, crisp and well defined reticle image.
3. If adjustment is necessary, follow the steps outlined for the type of Nightforce riflescope you have. Due to the way the human eye focuses, best results are usually obtained by turning the eyepiece inward until the reticle is slightly blurred then moving it outward until sharp focus is obtained. Refer to Figure 1. Reticle Focus Adjustment Grasp the eyepiece with one hand and the locking ring with the other and rotate the eyepiece counter-clockwise, turning it away from the lock-ring while holding the lock-ring and the riflescope to keep them from turning with the eyepiece. Several turns of the eyepiece may be necessary to achieve any measurable difference. To achieve an out-of-focus starting point for your vision, you may need to turn the lock-ring several turns inward first, then turn the eyepiece inward as needed to achieve an outof-focus position. Once the desired reticle focus is achieved, lock the eyepiece in place by turning the lock-ring into firm contact with the eyepiece while holding the eyepiece in position. Tighten the lock-ring against the eyepiece. If the reticle tends to fade in and out of focus, or you are experiencing eye strain with extended shooting sessions, that is an indicator that the reticle is not properly focused for your eye. Once you have achieved the best focus possible using the method above, it is recommended that you fine-tune
the focus one to two turns in either direction, on a target at 100 to 200 yards. Use a target of medium value such as light tan or gray rather than white for best results. A properly focused reticle will remain sharp for extended periods.
