I don't have a 30 mm eyepiece but I do have a 25 mm Plossl. Will that work?As for CA...at low magnifications with the scope I just don't see much of it. The image looks very "clean" with no noticeable color fringing present. I do start to notice it slightly once I hit 35x or so and then it becomes noticeably more prevalent above that. It is quite noticeable at the full 60x but I did not find it detrimental to the extent that it takes away from reading fine details at that magnification. I had the scope out yesterday and was reading a yellow/black neck band on a Snow Goose at about 200-250 yards and though CA was noticeably present in the image it did not take away from my ability to read the numbers on the neck band.I will also take the scope out on the next starry night and take a look at what type of results I get from the star test. They are calling for snow later today so it might not be for a day or two.</blockquote>
