Today, in the store, I observed models of atoms 8, 10, and 12 a total of three times. Pictures taken with 10x and 12x models equipped with a 25mm lens were of an unsatisfactory quality. The image in the left half of both sets of binoculars (!) had a bad chromatism, which caused the contrast to be poor and caused the picture to break up into yellow and blue colors. The 8 * 21 device, which was purchased as a present, had a quality that was surprisingly adequate. I can't say for certain that all of the examples are the same. There could be a significant gap in quality between the production and the retailer.
