The exciting new 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 constrasty image. Naturally, the Mak-Newtonian is an excellent visual performer, too.
