The StarSense Explorer 10” is great for Solar System objects too. Mercury and Venus show their phases, the Moon looks amazing, and Mars’ various features such as dust storms, ice caps, and some dark marking can be seen; when Mars is around opposition spotting actual geological features like Valles Marineris and Olympus Mons is even possible. Jupiter looks brilliant, covered in vivid cloud bands with the Great Red Spot showing itself prominently, and its moons are obvious disks during transits in front of the planet, with shadows following close behind. Ganymede even shows a color differentiation, corresponding to the feature known as Galileo Regio, while the tiny volcanoes and craters Io and Callisto appear as a speckled texture on the two moons.
