Although the focal ratio is not ideal for planetary detail, the 253mm aperture is so wide the amount of detail you can gather from the Solar System is mesmerizing.
Jupiter’s many stripes, The Great Red Spot, its 4 Galilean Moon’s are all easily visible with phenomenal color accuracy.
Rings of Saturn, The Cassini Divison, its many moons and its largest moon Titan are visible with noticeable color.
Mars will show its surface with black and white stains covering it. A couple of its moons may be visible on ideal conditions.
Phases of Venus are easy to observe with some faint, yellowish color.
Neptune and Uranus will appear as blueish dots, with Triton orbiting Neptune.
Mercury and Pluto are hard to observe with any telescope. They will appear as tiny dots most of the time, or they won’t be observable at all.
The Moon will show a ridiculous amount of craters and mountain ranges, with on-point color accuracy.
Overall the planetary performance is top-notch. As long as you are gathering light with a 253mm-wide tube, it is hard to screw up planetary performance.
There is one thing I have to mention in this section. Don’t get a Barlow Lens for planetary detail. It will ruin the images by adding an additional layer. A specialized eyepiece is a much better choice.
