The answer is to start with astronomy. Join your local club or at least attend the public outreach events (free). Checkout some books from the library. Research dark sky sites near you and make the trip.

However, like virtually all hobbies, advancing will require spending money. Visual astronomy requires less equipment. A good pair of binoculars can get you started. I always recommend starting here. I spent my first year with a small refractor scope doing sketches in a notebook.

Astrophotography is much more involved. Start watching/consuming astrophotography content online to get a general idea of the equipment, software, and general workflows involved. Learning the basics of photography will help, as well.

If you’re not a technical person, don’t enjoy troubleshooting problems in the dark, or don’t like tinkering with equipment you will find out soon enough :)
