Explore Scientific's compact FirstLight 127mm f/15 Maksutov-Cassegrain Telescope is ideal for users who want a portable yet powerful optical tube assembly (OTA) 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 split tricky binary stars and view brighter deep-sky objects.

The Maksutov design exchanges the conventional front corrector plate of a Schmidt with a convex meniscus lens, resulting in a smaller secondary mirror that limits obstruction and increases contrast, while eliminating the need for periodic collimation. This modified optical path results in a slower focal ratio and narrower field of view versus a similar Schmidt, but the optical benefits, when coupled with the larger aperture and fully multi-coated optics, make this an ideal scope for making detailed solar, lunar, and planetary observations, while being able to resolve deep-sky objects like stars, clusters, galaxies, and nebulae.

Offered here without a mount or tripod, this version of the FL MAK comes with a Vixen-style dovetail attached to the bottom of the optical tube for easy compatibility with a wide variety of mounts. It is ideal for users who already have a reliable support system and are looking to add to their observation arsenal, or for those building an a la carte rig. Explore Scientific includes several accessories including a 25mm eyepiece that yields a low 76x power, a 90° star diagonal that puts the user's head in a comfortable viewing angle, a universal smartphone eyepiece adapter for easy astrophotography, and a wide-field unmagnified red-dot finderscope.

Optical Tube

  • 127mm aperture makes the scope ideal for lunar and planetary viewing, with the ability to resolve deep-sky objects like binary stars and clusters
  • Relatively slow f/15 focal ratio translates to longer exposure times for astrophotography
  • Long 1900mm focal length provides a high magnification potential
  • Compact Maksutov-Cassegrain optical configuration is small and compact without sacrificing performance
  • 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

Mounting

  • Optical tube only; Mount and tripod required for proper use
  • Vixen-style dovetail bar is compatible with a wide variety of mounts on the market, including Alt-Az, EQ, and GoTo

Included Accessories

  • 1.25" 25mm Plössl eyepiece yields 76x magnification
  • 1.25" 90° star diagonal places head in comfortable position, especially when OTA is aimed high overhead
  • Smartphone adapter attaches over eyepiece and allows any smartphone to be used for astrophotography
  • Red-dot finder: Unmagnified for fast subject acquisition with variable red illumination to protect night-adjusted vision; mounting bracket included
