The Skylux Maksutov-Newtonian from Sky-Watcher is just what astrophotographers and serious visual observers have been looking for. The fast photographic speed of f/5.3 ensures short exposure times, and the 1,000mm focal length offers a fine compromise between image scale for detail and wide field for those larger objects.

The Mak-Newtonian design provides large aperture apochromatic performance with exceptional field correction in a compact, affordable package. Compared to a similarly sized Schmidt-Newtonian, the Mak-Newtonian yields a sharper and more contrasty image. Naturally, the Mak-Newtonian is an excellent visual performer, too.

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.

Optical focus is achieved by means of a mechanically ultra-smooth, backlash-free, precision 2” Crayford focuser-assembly. This focuser offers fine and ultra-fine focusing adjustments.

Large 64mm secondary mirror increases field illumination for optimal use with larger CCDs. The secondary mirror obstruction by diameter is 34%, and by area 11%.
