Description

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.”
