More about the product

Sky-Watcher Professional ESPRIT 3-Element ED apochromatic refractors offer optical performance rivalling similar telescopes from even the most famous high-end brands.

Designed primarily for demanding astro-imagers wanting high-contrast images full of detail and zero detectable colour fringing, even on the brightest of objects!  

An M48-fitting doublet field flattener is also available to flatten the field and minimise aberration and distortion. When used with the field flattener the Esprit-80's imaging circle is 33mm.

The M48 fitting provides a large clear aperture to reduce halation and a precision thread ensures the triplet and doublet lens groups are precisely aligned on the optical axis perpendicular to the image. 

Price includes storage case.
