Reticle focusing with eyepiece on 45

I have a ( Bukys frozen+TSI mounts ) Leupold 45 : i just found the locking ring unscrewed and wonder how much the eyepice has turned without noticing : i had no mark at the right spot . I just tried to focus it using the Leupold method or even with the help of what TB wrote and i see the reticle in focus on many turns of the reticle : anyone came up with a method to have a crisp reticle with no doubt ? What about a drop of nail varnish to lock the locking ring in place ? I plan to add my Davis booster (3,5x) :should i recheck after installing it ?
 
pascal,

A friend suggested that I tape a rring of masking tape around the eyepiece, adjust it in one direction until the crosshairs definitely go out of focus, mark the tape at a convenient point, then counting turns, go back the other way until achieving the same out of focus. Half way between both will be as good as you'll get the buggers - particularly if your eyes are as old & problematic as mine.

Run the procedure after you install the booster.

PS: Watch out for your eye relief if you're free recoiling. I pushed my Zeiss frames into my forehead with my 8-32 NF BR equipped with a similar booster last weekend because I was just a shade out of position.
 
thanks Jackie . I think i found a focus : i marked a reference and put a drop of fly tying varnish to lock it temporarily .
I come to Houston may 11thto 13th . See ya all .
 
Have ya ever noticed = = =

that some scopes come with an easily movable focus ring at the rear of the ocular lense? Why do ya think the makers put them there and so easy to use? From my experience, especially with 6X scopes, the occular bell needs to be moved sometimes to clear thing up to the sharpest picture one can get. I find this true with my 40X Competition Leup as well. I have noticed that the Weavers I have seem to not need much, if any changes with the occular once set but some other scopes need it and quite often.
 
I find it important to quickly glance at the reticle and then look away. Otherwise, the eyes will adjust to bring the reticle at least partially into focus. You want the target and reticle to be simultaneously in focus immediately.

Keeping the locking ring tight is critical. To convince yourself of this, try lightly pressing sideways on a loose ocular while you are looking through the scope and see how POA changes.

Cheers,
Keith

I had the same eye piece focus assembly coming loose problem with my new Leupold Hunter 6X scope. While a few drops of "blue Loctite" will solve the problem, I pulled a small diameter "O-ring" over the unit and installed it between the focus assembly lock ring and tightened the unit against it. Works great while still giving the ability to change focus if necessary (seldom required).

Actually the POA does not change with a loose ocular lens. If you loosen it and watch closely your POA remains the same on the target. The target and reticle image do move,but they move together. All a tight lockring does is keep the eyeshell from rattling around, it will have no effect on accuracy. Now the objective end being loose is a different story!!!!
