Balancing aperture with manageability and representing one of the widest apertures in the series, the Sky-Watcher 150mm f/12 Maksutov-Cassegrain Telescope is powerful while maintaining the portability of the smaller models. 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, makes 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.

The scope is outfitted with a large 2" visual back and to get users started, Sky-Watcher includes a 28mm long eye relief eyepiece that produces a moderate 64x magnification, and a 90° star diagonal for viewing with the OTA pointed at or near the celestial zenith. The OTA is offered here without a mount or tripod for users that have a reliable support system, or want to use it as part of a dual-OTA set up for star-parties or observation/imaging rigs. It is outfitted with a Vixen-style dovetail plate for use with compatible mounts. This OTA's compact form-factor belies its observation power and resolution and is ideally suited as a grab-and-go option for quick observation sessions or heading out to remote locations.

Optical Performance
  • 150mm aperture
  • f/12 focal ratio
  • 1800mm focal length
  • Front convex meniscus lens corrects spherical and chromatic aberrations, and comas (off-axis aberration) across the entire field of view
  • Smaller secondary mirror versus Schmidt-Cassegrains reduces obstructions and increases contrast
  • Fully multi-coated optics maximize light transmission to improve brightness, color rendition, sharpness and contrast
  • Resolution: 0.77 arcsec; Dawes
  • Internal primary mirror focus
  • 2" diameter visual back accepts larger eyepieces and accessories
Mounting
  • Requires mount and tripod for proper use
  • Vixen-style dovetail plate
  • Weight 14 pounds, including OTA and accessories
Included Accessories
    Eyepiece:
  • 2" barrel diameter
  • Accepts most 2" astronomical filters
  • 28mm eyepiece yields 64x power
  • Comfortable long eye relief
    Diagonal:
  • 2" snout and eyepiece holder
  • 90° angle places head in a comfortable viewing position
  • Star configuration corrects image horizontally for terrestrial use
    Finder:
  • Relatively low 8x magnification provides a wide field of view for easier alignment and faster star-hopping navigation
  • Larger 50mm aperture helps resolve dimmer objects that dot finders cannot
