I am getting lots of parallax from 200 yards on in regardless of how I turn the focus knob (the image is clear but the crosshairs are blurry and dance all over the place). I tried setting it to infinity and adjusting it aimed at a house about 1300 yards off and it's fine out there - no matter what I do though I can't get it to be parallax free before 200 yards. Is there something I'm missing or should I just send it back to loopie and let them muck around with it?
