Sky-Watcher Esprit 150ED APO Triplet
Product Features
The Esprit 80ED, 100ED, 120ED, and 150ED Super APO refractors feature an advanced doublet field flattener designed to produce a perfectly flat imaging field while minimizing distortion and optical aberrations. With a wide 48mm aperture, these telescopes deliver brighter and clearer views with halation reduced to a minimum. The triplet optics and field flattener are connected using a high-precision thin-thread system, ensuring the optical axis remains perfectly perpendicular to the imaging plane for optimal performance.
