Starplot is a Python library for creating star charts and maps.

  • ⭐ Zenith Plots - showing the stars from a specific time/location
  • πŸ—ΊοΈ Map Plots - including North/South polar and Mercator projections
  • πŸ”­ Optic Plots - simulates what you'll see through an optic (e.g. binoculars, telescope) from a time/location
  • πŸͺ Planets and Deep Sky Objects (DSOs)
  • 🎨 Custom Styles - for all objects
  • πŸ“₯ Export - png, svg, jpeg
  • 🧭 Label Collision Avoidance

Examples

Zenith plot of the stars from a specific time/location: starchart-blue

Map around the constellation Orion: map-orion

Optic plot of The Pleiades through a refractor as seen from a specific time/location: optic-pleiades

Basic Usage

To create a star chart for tonight's sky as seen from Palomar Mountain in California:

from datetime import datetime
from pytz import timezone
import starplot as sp

tz = timezone("America/Los_Angeles")

p = sp.MapPlot(
    projection=sp.Projection.ZENITH,
    lat=33.363484,
    lon=-116.836394,
    dt=datetime.now(tz).replace(hour=22),
    style=sp.styles.PlotStyle().extend(
        sp.styles.extensions.BLUE_MEDIUM,
        sp.styles.extensions.ZENITH,
    ),
    resolution=2000,
)
p.constellations()
p.stars(mag=4.6)
p.export("starchart.png")
