Galileoscope is easy to assemble without tools. I really liked the quality of design, workmanship and optics. With the included 20mm eyepiece the telescope gives a good 25x magnification of the moon and you can see the moons of Jupiter (it's not that hard - almost any binocular will show them) but also when conditions are dark and clear , a faint hint of streaks across the planet's disk. You can see Saturn's rings clearly, even though they are very small! If you have a Barlow lens, use it! Theโฆ
