Explore Scientific's compact FirstLight 100mm f/14 Alt-Az Maksutov-Cassegrain Telescope is a portable, yet powerful observation platform that can achieve high magnifications for detailed views of the moon and planets, and has the ability to reach out past our solar system to observe brighter deep-sky objects such as nebulae and galaxies.

The Maksutov-Cassegrain optical configuration is engineered with a convex meniscus lens which not only eliminates the need for periodic collimation, but the nature of the lens requires a smaller secondary mirror which limits obstruction and increases contrast. The Maksutov optical path results in a slower focal ratio and narrower field of view versus a similar Schmidt design, but the optical benefits make this a useful scope for planetary and double-star observation.

The scope features the manual Twilight Nano alt-azimuth mount with dual-axis control cables that allow users to track objects as they move across the night sky. Its stainless steel tripod provides a stable observation platform; and several observational accessories are provided that include a 25mm eyepiece, a 90°-star diagonal, a universal smartphone eyepiece adapter, and an unmagnified red-dot finderscope.
