Esprit 150ED APO Triplet
Esprit APO

Esprit 80ED, 100ED, 120ED and 150ED Super APO triplets have a doublet field flattener to get a flat field and minimize aberration and distortion.

Product Features

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. 

Main 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 

- Full-frame Corrected Focal Plane

- Zero detectable Colour Fringing even on Bright Objects

- Knife-edge Baffled Optical System

  • "The Esprit 150ED is an overall great performer offering excellent results."

  • "I can't stress enough how important a good focuser is for astronomical imaging. ...Focusing was fast and easy and the whole procedure became  second nature."

  • "...offers strong competition to the established refractors from Takahashi and TEC."
