Can You See It?
Resolving power matters.
 
             
  OPTICS  
 

One of the new innovations has been to marry cameras to spotting scopes, primarily used
for long-range photography. This is also an excellent way to determine both the resolving power
and contrast ability of the spotting scope and also the camera. This method removes the variable
of your visual acuity. This is the excellent Zeiss diascope and a Canon A2 SLR.

 
                     
 

A question often asked by competitors and long range shooters: “Is there a spotting scope that will allow me to see bullet holes at 400, 600 or 1,000 yards?” The answer to which is: Yes. Sometimes.

“Sometimes” is not a hedge. Being able to see fine detail revolves around the quality of the optic’s resolution, contrast, exit pupil, and aberrations as well as the viewer’s visual acuity, the amount of turbulent atmosphere through which you’re trying to see fine detail, and power.

That still begs the question: What is required of a spotting scope to allow me to see bullet holes in paper at long range?
