The Z61 isn’t the best telescope for visual astronomy – it’s not really designed for it, after all – but will work nicely with eyepieces and a 1.25” or 2” star diagonal. With a 2” diagonal and wide-field eyepieces you can take advantage of the Z61’s short focal length for huge vistas of open star clusters and the Milky Way. Planetary detail is possible with short focal length eyepieces or a Barlow lens. Expect to see the phases of Mercury and Venus, craters and mountains on the Moon, ice caps on Mars, the rings of Saturn, and the moons and cloud belts of Jupiter. Uranus and Neptune are dots, and you can see a handful of globular clusters and galaxies, but none are of much excitement with aperture this small. With light-polluted skies, you will struggle to see any deep-sky objects at all with the Z61 apart from the brightest open clusters.
