S11550 Starlux 190MN Mak-Newtonian Telescope by Sky-Watcher
The exciting new Starlux 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 image with more contrast. Naturally, the Mak-Newtonian is an excellent visual performer, too.
