Planning your astrophotography session is essential. Indeed, not all stars are present all year round and it is therefore necessary to understand the seasonality of celestial objects. In addition to this, there are certain precautions to take so that your equipment functions correctly during the night, such as warming up or various very useful accessories.
 
We also discuss the notions of Bortle scale and Seeing in order to understand the quality of one's observation location and whether it is necessary to go elsewhere or not. Indeed, unfortunately we are not all equal when it comes to light pollution. So, what to do against it, how to protect yourself from it and what solutions to adopt? This is what we cover in this section. As for Seeing, which depends on atmospheric turbulence, it is also important to know the force because they have a direct effect on your equipment. Indeed, not all instruments and imagers are adapted according to Seeing and their sampling (lesson no. 5 is particularly devoted to this subject).
 
In the last part, we are interested in the phases of the moon and their impact on astrophotography to put all the chances on our side. Although she is sublimely beautiful, she can become our worst nightmare depending on the phase. Fortunately, there are different solutions that you can discover in this last section.
