: optical centering
: November 29, 2006, 01:00:21 PM
I read a post about optically centering a scope.  Thought I would give it a try with my Barska 3-12x40.  The post was sure correct that it isn't done quickly.  Is it best to attempt this with the power set to lowest setting?  I don't know if I may be doing something wrong or what, but I worked at it for about an hour this morning and it's still not dead on when I rotate it 360 degrees.  Can anyone give me any further advise on how to bring it into center?  I'm mounting to a CFX with a beeman adjustable mount if I ever get it centered.

I'm probably a bad example when it comes to the optical centering of a scope but, I've never been able to get it perfectly centered, for whatever reason. I'm not even sure if it's a necessity to get it perfectly centered, but then again, that's just me minimizing to justify my impatience.  :D    I've gotten scopes very close to center using that method but after about 30 to 45 minutes of playing around with it, I say the heck with it, it's close enough.  So far, I've been happy with the results, so it's really up to you.  Hope this helps. 8)

I have to agree with Mark, it doesn't need to be perfect, especially with an adjustable mount.  I center scopes in my shop, 40 feet from end to end, I just pick a spot on one of the doors, scope at minimum power.  After I get it as good as I think it will get, or when I run out of patience, then I jump to max power just to double check.  Remember, some scope CAN'T be perfectly centered, so close enough, is.
