Description

Sky-Watcher Esprit 80ED, 100ED, 120ED and 150ED Super APO refractors have a doublet field flattener to get a flat field and minimize aberration and distortion. Their wide 48mm opener ensures a larger and clearer aperture and also extremely minimized halation. Connect the triplet and doublet field flattener with a high precision thin thread to keep the optical axis perpendicular to the image.

Features:

  • Premium optical materials
  • Short focal length and full frame corrected focal plane
  • Excellent field flatness
  • Precision linear power focuser is standard
  • Metallic high-transmission lens coatings
  • Light-baffled optical systems
  • Telescope tube attachment hardware
  • Zero detectable colour fringing even on bright objects
  • Knife-edge baffled optical system

The kit includes:

  • Optical tube
  • 8x50 erect-image 90° finder scope
  • 2-element thread-on field flattener
  • Thread-on field flattener adaptor
  • 90° diagonal mirror, 2"
  • T-ring for Canon M48 cameras
  • Aluminum case for storage and transportation
  • User manual and warranty
