So the standard way to do this is:
Point scope at a plain bit of sky or white wall/piece of paper through the scope.
close your eyes
Open your eyes and adjust reticle focus.
repeat until you think the reticle is "sharpest"
When I do the above method with scopes that have an IR feature, the red/green/blue reticle seems slightly blurred and if there is a center dot, it always seems to have a star-burst effect. Yes, old eyes suck. Up until last night I just accepted the star-burst as part of aging. :-(
On a whim, I popped off the scope flip covers and started playing with the ocular focus. Mind you, I’d already gone through the standard reticle focusing routine.
I started on the lowest visible light setting for the IR and pointed to the darkest area in a room. Turned the ocular focus and noticed something pretty cool..the star-burst was being reduced. So I turned and focused to the point there was just a red dot. Then, I increased to a brighter IR setting and there was a micro star-burst..so I adjusted focus again until it was gone. Upped the IR setting and repeated. At one point, as I increased IR, there was no star bust effect. I checked by cycling downward in IR brightness and no star-burst at all.
Next day I looked through the scope in full sun and the reticle was crystal clear. Much better than is was originally.
