150/1050 SkyWatcher ESPRIT Triplet-APO set with original fullframe flattener and transport case

The new Sky-Watcher Professional ESPRIT 3-Element ED apochromatic refractors offer optical performance rivaling or exceeding 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 optically-matched doublet field flattener is also available to flatten the field and minimize aberration and distortion. When used with the field flattener the Esprit-150's imaging circle is 44mm.

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.
