When I got started with astrophotography, I quickly stumbled upon a lot of unknown terms, strange acronyms and mysterious abbreviations. The lexical of astronomy can be overwhelming! Besides, this vocabulary often hides complex notions of physics, optics, astronomy or meteorology.
For these reasons, I created this simple glossary. The idea is to give a simple explanation of these words, in a convenient way: every time I use one of these words, moving your mouse over it will display a small bubble explaining the word. Clicking on it will open a more detailed page.
I’m open to suggestions, so feel free to send me your feedback, and propose new words and definitions!
