[QUOTE="bruce_ventura, post: 768976, member: 34084"] Regarding mirage, I've spent a fair amount of time studying turbulence induced blur in tactical day optics. For hunting, I look at it this way. Turbulence blur always gets worse as the aperture increases. If you can see the target in your larger spotting scope well enough to judge the game animal, then the turbulence blur will be less in the rifle scope. If the blur is too bad in the spotting scope to judge the animal, the rifle scope may give you a better view. Sometimes the blur is just too bad to see any detail, regardless of the optic. The best approach is to avoid turbulence blur as much as possible. That means choosing a spot for classing that avoids long optical paths close to flat terrain. Raising the scope up even 12" higher will often noticeably reduce blur. If you go with 8-32X, always use a sunshade. Otherwise glare will be a frequent problem. [/QUOTE]
