You can adjust it under the night sky, I had the same thing happen. First center the reticle on Polaris. Then raise the altitude adjuster to move Polaris to the outer circle. If it lies on the 24h line, you're ok. Otherwise loosen the setscrew and rotate the reticle to lie on Polaris. Then lower the altitude adjuster to make sure Polaris moves back to the center point. Lock setscrew. Voila!

Ah this is a bad news.
I think I need to return the scope to AP for service.
I'm not confident that I can adjust that.
The unit needs dead on accuracy.
It is strange that this happens.
I never touched the set screw as instructed in the manual.
