Astromart.com: Megrez ED triplet APO Versus Megrez Fluorite Doublet

Megrez ED triplet APO versus megrez Fluorite Doublet.jpg

Fred Hissink posts an interesting comparison of the Megrez ED triplet APO and Megrez Fluorite Doublet telescopes on Astromart.com 'The big world of Apochromats, Extra low Dispersion and Fluorite is still a very confusing one; especially if you throw in some more marketing terms like SD, Fpl-53 and Super APO. It is difficult to understand the supposed differences with regard to color correction, but it is sometimes even harder to see those differences in the field. According to some optical experts, there should be a small difference in the degree of color correction between the Megrez ED triplet APO and the Megrez Fluorite Doublet (in the rest of this article referred to as Megrez ED and Megrez Fl.)

After some investigations on the Internet we found out that a direct comparison had yet to be made, so we decided to put the two boys up to the test. Comparing two scopes is a difficult task. We were about to compare a doublet and a triplet, with different optics and coatings. But the idea was to get an overall impression of the differences and perhaps similarities of the Megrez Brothers.
