There are many tutorials on various methods of sketching astronomical objects on the internet as well as the book I found entitled "Astronomical Sketching: A Step-by-Step introduction (The Patrick Moore Practical Astronomy Series). Not only is astronomical sketching a good way to learn detailed characteristics of astronomical objects in the world of astronomy education, it is also a great exercise for enhancing one's artistic skills. However, please keep in mind, it may take patience.
