Watching Jupiter, its Galilean moons and Saturn!

Last night I tried to watch both Jupiter and Saturn through my old telescope, which many amateur astronomers would claim it to be a “kids scope”. Despite the low quality of my equipment, I was surprised after watching Jupiter and its main moons together with Saturn and its rings. This posts includes some some drawings I made so you can better understand what exactly I saw.

When it comes to stars classification, the Hertzsprung-Russell diagram is probably the most popular way of doing so. These diagrams relate the temperature of the star and its luminosity. After plotting the values for different stars, several groups arise in the figure, which enable to distinguish between different types of stars.
