Sky-Watcher SKU: S11550 | Helix SKU: CTS11550

Overview


The exciting new Starlux Mak-Newtonian from Sky-Watcher is just what astrophotographers and serious visual observers have been looking for.

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.
