SkyWatcher Esprit 150ED F/7 triplet flat-field apochromatic refractor
SkyWatcher Esprit 150ED F/7 triplet flat-field apochromatic refractor features right angled erect image finder scope, 3" focuser, 2" diagonal with 1.25" adapter.
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.
