[QUOTE="bruce_ventura, post: 629034, member: 34084"] Turbulent air is often characterized as giving a good image up to a certain diameter, and blurred above that diameter. The worse the turbulence, the smaller the characteristic diameter over which the image is good. Under typical daytime conditions at a range, this diameter is usually less than 25 mm for targets at 100 yds and beyond. That diameter is smaller than most scope objectives. The larger the scope aperture, the more blur. [/QUOTE]
