Explore Scientific FirstLight 152 mm Maksutov-Cassegrain on the Twilight I Adjustable Alt-Azimuth
The Explore Scientific FirstLight 152 mm Maksutov-Cassegrain Telescope is ideal for users who want a portable yet powerful observation platform that is able to 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.
Its Maksutov-Cassegrain optical configuration is engineered with a convex meniscus lens that not only eliminates the need for periodic collimation but by the nature of the lens requires a smaller secondary mirror that limits obstruction and increases contrast.
The Maksutov optical path results in a slower focal ratio and a narrower field of view versus a similar Schmidt design. The optical benefits make this a useful scope for planetary and double-star observation.
Compact Maksutov-Cassegrain optical configuration
Front convex meniscus lens corrects spherical and chromatic aberrations and comas (off-axis aberrations) across the entire field of view
Smaller secondary mirror versus Schmidt-Cassegrains reduces obstructions and increases contrast and sharpness
Internal focusing mechanism with 1.25" visual back
