Starplot is a Python library for creating star charts and maps.
- β Zenith Plots - showing the stars from a specific time/location
- πΊοΈ Map Plots - including North/South polar and Mercator projections
- π Optic Plots - simulates what you'll see through an optic (e.g. binoculars, telescope) from a time/location
- πͺ Planets and Deep Sky Objects (DSOs)
- π¨ Custom Styles - for all objects
- π₯ Export - png, svg, jpeg
- π§ Label Collision Avoidance

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")For a demo of Starplot's zenith plots, check out:
