Yes. Most consumer telescopes can be used for terrestrial viewing (or at least the ones I have used) and are often utilized for wildlife viewing or other uses for extreme telephoto requirements.
Seeing Jupiter's Moons Even a set of 10x binoculars will be enough to see Jupiter's four largest Moons—Io, Europa, Ganymede, and Callisto. They look like tiny “stars” crossing Jupiter. No telescope needed.
Pluto is distant, about 3 billion miles from the Sun. You can see where it is in the night sky, just above the handle of the teapot shape of the constellation Sagittarius, rising about 10 p.m. But don't expect to spot it with your binoculars; it's too small (smaller than our moon) and too dim.
A pair of 7×35's is about the minimum acceptable for astronomical observing; 7×50's are better… this will give you the same magnification but a wider field of view. These 9×63 binoculars by Celestron give bright images but they are about as heavy as most people can use without a tripod.
Neptune varies from magnitude 7.8 to 8.0, about two magnitudes fainter than Uranus. It's visible in steadily-supported binoculars, but only if you look quite carefully.
Binoculars are suitable for viewing the Moon, especially if you wish to see the full lunar disc and want a quick view, with minimal set-up time. Also, binoculars are extremely portable.
Step 2 – Finding Mercury Without a Telescope During its better apparitions, those when it is highest in the sky 45 minutes after sunset or before sunrise, it can be seen with the naked eye or simple binoculars.
Telescopes are a useful tool, but they do not teach you the night sky. Often, they can be frustrating if you get one before you're ready. We recommend starting with a sky map to build some familiarity. Learn a few constellations, watch for the Moon's changing phases, and find a planet if any are visible.
The flag on the moon is 125cm (4 feet) long. You would require a telescope around 200 meters in diameter to see it. The largest telescope now is the Keck Telescope in Hawaii at 10 meters in diameter. Even the Hubble Space telescope is only 2.4 meters in diameter.
The rings of Saturn should be visible in even the smallest telescope at 25x [magnified by 25 times]. A good 3-inch scope at 50x [magnified by 50 times] can show them as a separate structure detached on all sides from the ball of the planet.
