Product Highlights

  • 102mm Aperture Maksutov-Cassegrain OTA
  • 1300mm Focal Length, f/13 Focal Ratio
  • Limited-Diffraction Optical System
  • Fully Multi-Coated Optics
  • Internal Primary Mirror Focusing System
  • 25 & 10mm 1.25" Eyepieces
  • 1.25" 90° Star Diagonal
  • Red Dot Finderscope
  • Vixen-Style Dovetail Plate
  • OTA Only - Mount and Tripod Required

Similar to their Schmidt cousins, this 102mm f/13 Maksutov-Cassegrain Telescope from Sky-Watcher exchanges the conventional front corrector plate with a convex meniscus lens, which results in a smaller secondary mirrorlimiting 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 the optical benefits, when coupled with the larger aperture and fully multi-coated optics, make this an ideal scope for solar, lunar, planetary, and deep-sky observation of bright objects like stars and clusters.

The scope is outfitted with a 1.25" visual back and, to get users started, Sky-Watcher includes 10 and 25mm eyepieces that produce low and moderate magnifications and a 90° star diagonal for more comfortable viewing when the optical tube assembly (OTA) is pointed at or near the celestial zenith. The OTA is offered here without a mount or tripod for users who have a platform or want to use it as part of a dual-OTA setup for star parties or observation/imaging rigs. It is outfitted with a Vixen-style dovetail plate for easy attachment onto many 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
  • 102mm aperture
  • f/13 focal ratio
  • 1300mm focal length
  • 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
  • Fully multi-coated optics maximize light transmission to improve brightness, color rendition, sharpness, and contrast
  • Resolution: 1.01 arcsec
  • Internal primary mirror focus
  • 1.25"-diameter visual back takes 1.25” eyepieces and accessories 
  • Requires user-supplied mount and tripod
  • Vixen-style dovetail plate
  • Weight: 4.6 pounds including OTA, dovetail plate, finder, diagonal, and eyepiece
Included Accessories
  • Eyepieces:
  • 1.25" barrel diameter
  • Accept most 1.25" astronomical filters
  • 25mm eyepiece yields 52x power
  • 10mm eyepiece produces 130x magnification
  • Diagonal:
  • 1.25" snout and eyepiece holder
  • 90° angle places head in a comfortable viewing position
  • Star configuration corrects image horizontally for terrestrial use
  • Finderscope:
  • Unmagnified view provides a wide field of view for easier alignment and faster star-hopping navigation
  • Red center aiming dot won't obstruct objects
  • Variable intensity to preserve night-adjusted vision
