The cratered landscape of the Moon is also well worth observing, and you can watch this changing with the different lighting conditions arising from the changing phase. Fascinating nature watching during daylight hours is also possible by adding an erecting lens or an Amici prism. Focusing is carried out by means of an adjustment knob on the rack and pinion focuser. This allows the focusing sharpness to be always precisely set and for it to remain fixed during observing.
This is also a useful acquisition for advanced astronomers or when changing to a more powerful system as the optics are well suited for use as a guide scope which can be mounted on top of a larger telescope and used to take pictures or to guide with.
