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).
RA (h m s) | Dec (degrees) | Abbreviation 13 03 16.9470 | 76.3289108 | UMI 13 04 23.3937 | 69.3293610 | UMI 14 02 36.1947 | 69.3991165 | UMI 14 03 16.9333 | 65.3996506 | UMI 15 41 19.0957 | 65.6023483 | UMI
The 0h / 24h meridian is continuous. A coordinate jump there should not be treated as a straight line across a flat map.
