How to read this chart
Dots mark stars, and their sizes indicate brightness. Stars appear dark on light charts and light on dark charts. Green lines show a constellation pattern. The surrounding grid gives right ascension and declination.
This is a fixed reference map, rather than a view of tonight’s sky.

The boundary marks a sky region; it is separate from the green star pattern. These files preserve ordered coordinate points in the J2000 reference system.

Right ascension uses hours, minutes and seconds. Declination is in degrees. Convert right ascension to degrees with 15 × (hours + minutes/60 + seconds/3600).

The 0h / 24h meridian is continuous. A coordinate jump there should not be treated as a straight line across a flat map.
