Maksutov-Newtonians
Product Features

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. 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. 
 

Schott Glass 

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. 

Tube Materials 

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. 

Precision 2” Crayford Focuser as Standard 

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. 

Secondary Mirror

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