Start with the sky you can see.
A clear view and a familiar place are enough for a first page.
Choose a comfortable, accessible place after dark and spend a moment looking around before looking up. Notice the buildings, trees, and nearby lights that shape your view. Those features can become useful reference points when you return.
Begin without trying to identify everything. Pick one visible pattern or bright point and describe where it sits relative to the horizon. If you want a name, use a current sky chart or a trusted astronomy guide set for your location and time. Treat the illustration on this page as atmosphere, not as a map of tonight’s sky.
Give yourself time away from bright screens where practical. Keep any light you need directed toward your notes and the ground. A short, comfortable session can be more useful than an ambitious plan that leaves little attention for the sky itself.
You do not need to buy equipment before deciding whether you enjoy the habit. First learn what is visible from a place you can visit easily. Later choices will make more sense when they answer a question you already have.
