Oh, if we had a nickel for every time we've been asked, "When are you going to come out with a bigger (than 127mm) Mak?" We'd be writing this from our branch office on the Maui beachfront. Cut from island fantasy to astronomy fantasy ... because we've got what you have been wishing for. Our 150mm Mak opens up new vistas of the celestial landscape for your viewing pleasure, putting superior resolving power at your disposal. The 150mm-diameter Maksutov-Cassegrain optics take in 40% more light than their 127mm counterpart, which means this big Mak will resolve finer detail in lunar and planetary subjects and permit exploration of a wider array of deep-sky objects. The meniscus lens is fully multi-coated for maximum light transmission. The long focal length of 1800mm (f/12.0) belies the scope's compact tube, which measures just 17" long (including visual back on rear cell), for excellent portability. Also available: SkyView Pro 150 EQ Mak (#9968).
