Set up a target at the maximum distance possible.Set up a time to hit the range and take full advantage to calibrate your AO settings for your eyesight. In this case, you can disregard the reference markings and make your own. Remember how I said reference markings are just that - references? That's because the markings might not always be completely accurate with your image quality while getting rid of parallax. The Weaver 40/44 Series 6.5-20X44 AO has an adjustable objective and costs less than $200.īut, some people choose to do it and it provides a more accurate and faster way to get parallax free for that known distance. Out of focus In focus Out of focus vs in-focus reticle - Images by Chris 'The Optics Nut' (Own Work) for Target Tamers Look back through the scope and repeat the process until the reticle is sharp, crisp, and as black as can be.While looking away, make the adjustments with the eyepiece.This is to prevent eye muscles from focusing and correcting the image for you. Just look through the scope to a blank backdrop such as a wall.There's no way you can adjust for parallax and get dead on if the foundation hasn't been cemented in. The goal of focusing is to get the reticle focused for your set of eyes. Once you've got the most comfortable and most practical position behind the wheel, you shouldn't have to adjust any of those components again. It's like getting back in the drivers seat after someone borrowed your car - you need to adjust the mirrors, the seat position, and perhaps even the steering wheel and pedal heights. Now that I've got you up to speed on your internal anatomy, let's uncover why you may have never heard of or dealt with parallax until now.įast focus eyepiece on the Vortex Optics Strike Eagle 1-8x24 FFP scope - Image by Tina Fa'apoi (Own Work) for Target Tamersīefore we jump the gun, ensure your scope is focused for your eyes first.įocusing a rifle scope is a one time adjustment that shouldn't be done again unless someone else used your scope. By turning the AO to the appropriate distance referenced on the outer surface, it will shift the objective lens assembly until your reticle and image are in the same focal plane. Objective lens - the objective lens assembly's position is what's adjusted to correct for parallax when using an adjustable objective (AO). If you turn the side focus knob to a lower distance, it will shift closer in the direction of the ocular lens assembly. As you turn the side focus knob to a higher distance reference (marked on the knob) towards infinity, the entire focus assembly shifts closer to the objective lens assembly.
