Little refractors are ideal tools for widely spaced but grossly unequal magnitude doubles. Try it!



I have, and it appears you raise a good point. It does seem my obstructed CAT struggles with unequal pairs, especially within a range of separations and deltaM. But, on close equal pairs it holds it's own. I have not been able to split the pup, either.

Still, it mathces closely descriptions and images of Jupiter from refractors an inch or two smaller in aperture. It stays well tuned and under pretty stable tropical skies. The seeing is regularly good enough to let it work at full aperture in terms of resolution and contrast. (Often, I thank God for those jaw dropping moments.)
