Edmund Newtonian reflector. The central obstruction is only 16 percent and is supported by a thin single stalk.
Coatings are fairly good but by no means excellent.
The planets showed more detail in the 6-inch telescope. Saturn was brighter and whiter compared to the 5-inch, and showed finer object detail at higher powers. Saturn was golden in the 5-inch and also showed many fine details, including a sharply defined Cassini's division, the Crepe ring and the rather elusive equatorial belt. Jupiter showed similar rich color saturation, with brownish cloud belts and a pinkish Great Red Spot within the larger Red Spot Hollow. Similar results were obtained when observing the moon.
