Micro-lesson 1
Eyes first
This courtyard is the porch. The last ones were ideas. These are the things you actually take into the dark.
Your first instrument is already on your face.
Give it 10–15 minutes in the dark. Bright phone light resets that clock. Face away from streetlights.
Averted vision: look a little beside a faint fuzzy, not straight at it. The side of your eye is better at dim glow.
Still never stare at the Sun. Not with eyes, not with binoculars, not with a telescope, unless the tool is built for it.
