Starplot is a Python library for creating star charts and maps of the sky.
- ⭐ Zenith Plots - shows the entire sky at a specific time and place
- 🗺️ Map Plots - including many map projections
- 🌃 Horizon Plots - shows the horizon at a specific time and place
- 🔭 Optic Plots - shows what you'll see through an optic (e.g. telescope) at a specific time and place
- 🪐 Planets and Deep Sky Objects (DSOs) - more than 14,000 objects built-in
- 🎨 Custom Styles - for all objects
- 📥 Export - png, svg, jpeg
- 🧭 Label Collision Avoidance
Zenith plot of the stars from a specific time/location:
Map around the constellation Orion:
The Pleiades star cluster, as seen through a refractor telescope from a specific time and location:
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,
),
resolution=4096,
autoscale=True,
)
p.constellations()
p.stars(mag=4.6)
p.constellation_labels()
p.export("starchart.png")
