ED Doublet Refractors — Sharp, Color-Corrected Performance for Visual & Imaging
An ED doublet refractor is a sweet spot for observers who want clean, high-contrast views with strong
chromatic aberration control—while keeping the optical design practical for everyday use.
These scopes are excellent for Moon & planets, bright deep-sky targets, and
astrophotography when paired with the right reducer or field flattener.
Quick tip: For imaging, double-check your spacing and field correction. The ED80 kit is designed to work well for imaging
when used with Starfield reducers or flatteners, and the ED102 is described as color-free even at high magnification.
