Planetary observation is a strength of these instruments and the necessary magnification is easily obtained by stacking two or three barlow lenses. Chromatic aberration is an important criterion and these scopes have plenty of it. Higher quality scopes use exotic and expensive lenses that can actually reduce chromatic aberration to that of a good f/15 Tasco. With these points in mind, I set out to find my ideal scope.
