One younger guy, with good eyes, said immediately: Yeah, I can see the holes right there at 4 oclock and seven oclock. As soon as the first practice targets went up, to my surprise, I could see 6. We easily put the scope on the tripod with a knob under the scope. By 10: 00 am at my range, even with the 100mm Pentax at 75 power, seeing 6mm bullet holes is iffy at best. Keep in mind that the Pentax does have ED or low-dispersion glass, so the effect would be even more dramatic with a cheaper spotting scope. 00 by itself, or you can get the PF-100ED with a 26-78X zoom lens for about $1900. 00 price, this eyepiece is extremely clear and sharp. I also liked the small size of it. This fringing is caused by chromatic aberration the failure of a lens to focus all colors to the same point. But again, that
Plus, weve heard reports that Zeiss is working on a new APO Über-scope for release next year. Thats right, I could see bullet holes at dawn, by mid-morning I could barely read the numbers on the scoring rings. With an aspherical lens surface and APO-corrected quality, this lens sets new standards in the category of short telephoto lenses. So given the choice a better tripod would have been nice. ) Mirage Degrades Image Sharpness and ResolutionThe magic light prevailed for only an hour or so, and then we started to get some mirage. Befitting its $359. Some older guys, who were wearing glasses, could not see the holes at all, no matter what we did to the scopes main focus and diopter adjustment. Any scope that can resolve bullet holes at 1000 yards is impressive. It's a little less than 14 inches long and on the tripod is about 14 inches high. Chromatic aberration manifests itself
And when I looked at the 30-cal targets, the bullet holes in the white at 1000 yards. The Pentax PF-100ED is a heck of a spotting scope. Plus, weve heard reports that Zeiss is working on a new APO Über-scope for release next year. Wow. On one side of the bright, white spotting disc you could see a dark red edge, while on the other side there was a blue edge (harder to see but still present) . 00 by itself, or you can get the PF-100ED with a 26-78X zoom lens for about $1900. Basically anything that goes between the scope eyepiece and your eyeball can degrade the image somewhat. Chromatic aberration manifests itself as fringes of color along boundaries that separate dark and bright parts of the image, because each color in the optical spectrum cannot be focused at a single common point on the optical axis. When used with the 100mm Pentax scope, this
And when I looked at the 30-cal targets, the bullet holes in the white at 1000 yards. But again, that performance requires really good viewing conditions. Keep in mind that the Pentax does have ED or low-dispersion glass, so the effect would be even more dramatic with a cheaper spotting scope. barska. Plus, weve heard reports that Zeiss is working on a new APO Über-scope for release next year. It is also excellent for quick snapshots when you want to take pictures inconspicuously from a distance. The sharpness of the Pentax was actually much better than this photo shows, but the through-the-lens image does clearly reveal the red and blue fringing. Chromatic Aberration RevealedAs the light got brighter and the mirage increased I started to see blue and red fringing at the edges of the spotting disk and the large numerals. In these perfect conditions I could also make out 3/8
