DESC: 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.
