Disapointing I have been using this thing for two weeks now and, it is safe to say that it wont get any better with more experienced handling from my part,because i had test it a lot. Here is what i found: 30x Image quality is ok, but around 45x image degrades very badly, chromatic aberration apears, and a contour of color can be seen arround objects; and it get so much wors at 60x because things start to get out of focus,. when you get to 90x, besides chromatic aberration, it is notorious a severe spherical aberration of the lenses, and no mater how many turns you give to the focusing knob nor how fine you adjust it, it will not focus at all, so the image is deficient in color, luminosity and focus. The telescope is a hugh pice of crap for zooms beyond 40x.
