i have the swfa 3-9x and spent about 2 hours today adjusting the reticle focus by looking at the sky. At first, i did not know you aren't suppose to look at the reticle while turning the focus ring. I'm a newbie, but there is a lot of turning of the ring with seemingly no effect on the reticle. The reticle looks clear, but it also looked clear before i did a few turns. What are some tips to set it correctly and verify it is correct?

Opinion,untempered by fact,is ignorance.
There are some who do not fear death... for they are more afraid of not really living |

That was a good read, but did not find any new tips. I heard the reticle is set for 20/20 vision when it is all the way in and backing it out is if you have worse eyesight. Right now I have the lock ring away from the magnification ring as little as possible so it does not hit it and the reticle ring bumped against it. The reticle looks clear and focused - good enough i suppose. what bothers me is it always was in focus no matter where i set it. this makes me think i am screwing something up but just don't know it yet.
I've been doing this against a cloudy white sky, 9x magnification |

If you look at it to long your eyes will adjust to the reticle, rather than adjusting the reticle to the eye. look Blink look away then look back. then repeat. The reticle is 20/20 in the middle, not one end or the other. In and out is for +/- diopter change to match your prescription.

Folks ain't got a sense of humor no more. They don't laugh they just get sore.
Need to follow the rules. Just hard to determine which set of rules to follow Now the rules have changed again. |

What 3_tens said is correct.
Look away at some distant object and let your eyes relax. Then look through the scope at the sky and see if the reticle looks sharp IMMEDIATELY. Do not let your eyes adjust and refocus. If the reticle is not sharp, adjust the eyepiece a little and repeat. ILya
