iOptron SmartStar Cube-A MC90 90mm f/13.3 Maksutov-Cassegrain GoTo GPS Telescope

An ideal choice for astronomical viewing and astrophotography, the iOptron SmartStar Cube-A MC90 90mm f/13.3 Maksutov-Cassegrain GoTo GPS Telescope is for users who want a compact and powerful observation platform that is able to make detailed views of the Moon and planets with the ability to reach outside our solar system. The Maksutov-Cassegrain design uses a front corrector plate with a convex meniscus lens to correct off-axis aberrations, like comas, and chromatic aberration to produce images with true-color rendition. The nature of the lens results in a smaller secondary mirror—limiting obstruction and increasing contrast, while eliminating the need for periodic collimation. The Maksutov optical path results in a slower focal ratio and narrower field of view versus a similar Schmidt, but for many the optical benefits are worth it.
