The ZenithStar 73 is not an ideal telescope to purchase for visual observation due to its price and small aperture, but it can still be fun to use with suitable high-quality eyepieces and a star diagonal. The short focal length allows for expansive views of open star clusters and the Milky Way, particularly with a 2” diagonal and eyepiece. With the help of a 2-3x Barlow lens or very short focal length eyepieces, it is possible to use the ZenithStar 73 to observe the most obvious planetary features such as the phases of Venus and Mercury, lunar craters and mountains, Mars’ ice caps, Saturn’s rings, and the moons and cloud belts of Jupiter. Uranus and Neptune will be hard to tell apart from stars with such a small aperture. While a few globular clusters and galaxies can be seen, the small aperture of the ZenithStar 73 means they’ll be little more than featureless fuzzy balls; the fun is mainly in viewing open star clusters, or large nebulae with the aid of dark skies and a high-quality nebula filter.
