The Mak-Newtonian from Sky-Watcher is just what astrophotographers and serious visual observers have been looking for.
The Mak-Newtonian design provides large aperture apochromatic performance with exceptional field correction in a compact, affordable package.

Sky-Watcher Maksutov-Newtonian Series benefit from the inclusion of Schott glass being used for the positive front Crown element in the objective. Schott is the recognized world leader in glass utilized for precision optical lens systems, including medical instrumentation, and famous-brand camera lenses.
The optical tube material is rolled steel, powder-coated reflective gloss black with gold fleck accent. The front and back cells are cast-aluminum painted white, or black.
