When we start or want to start doing astrophotography we don't have the slightest idea of what equipment is required to do it. Then we ask people who are already immersed in the hobby or look for articles about it, but sometimes at the end we find information with so much detail that it is complicated to have an idea of what is needed.
This is why I present a general idea without going into too much detail of the most common elements used in astrophotography so that those who are starting almost from scratch can get the big picture about the equipment required. The detail of accessories at the moment of buying each equipment will be described in later articles.
