including 10+ customizable projections\n- ⭐ **Zenith Charts** - shows the entire sky at a specific time and place\n- 🌃 **Horizon Charts** - shows the horizon at a specific time and place\n- 🔭 **Optic Simulations** - shows what you'll see through an optic (e.g. telescope) at a specific time and place\n- 🪐 **Planets and Deep Sky Objects (DSOs)** - with support for plotting their true extent\n- ☄️ **Comets and Satellites** - easy trajectory plotting\n- 🎨 **Custom Styles** - for all objects and with 8+ built-in themes\n- 📥 **Export** - png, svg, jpeg\n- 🚀 **Data Backend** - powered by DuckDB + Ibis for fast object lookup\n- 📓 **Custom Data Catalogs** - with helpers for building and optimizing\n- 🧭 **Label Collision Avoidance** - ensuring all labels are readable\n- 🌐 **Localization** - label translations for French, Chinese, and Persian (coming soon!)\n\n## Examples\n*Zenith chart of the stars from a specific time/location:*\n![starchart-blue](https://starplot.dev/images/examples/star_chart_basic.png)\n\n*Map around the constellation Orion:*\n![map-orion](https://starplot.dev/images/examples/map_orion.png)\n\n*The Pleiades star cluster, as seen through a refractor telescope from a specific time and location:*\n![optic-pleiades](https://starplot.dev/images/examples/optic_m45.png)\n\n## Basic Usage\n\nTo create a star chart for tonight's sky as seen from [Palomar Mountain](https://en.wikipedia.org/wiki/Palomar_Mountain) in California:\n\n```python\nfrom datetime import datetime\nfrom zoneinfo import ZoneInfo\n\nfrom starplot import ZenithPlot, Observer, styles, _\n\ntz = ZoneInfo(\"America/Los_Angeles\")\ndt = datetime.now(tz).replace(hour=22)\n\nobserver = Observer(\n    dt=dt,\n    lat=33.363484,\n    lon=-116.836394,\n)\n\np = ZenithPlot(\n    observer=observer,\n    style=styles.PlotStyle().extend(\n        styles.extensions.BLUE_MEDIUM,\n    ),\n    resolution=4096,\n    autoscale=True,\n)\np.constellations()\np.stars(where=[_.magnitude \u003c 4.6])\np.constellation_labels()\np.horizon()\np.export(\"starchart.png\")\n```\n\n## Documentation\n\n[https://starplot.dev](https://starplot.dev)\n\n\n## Demo\nFor a demo of Starplot's zenith charts, check out: \n\n[Sky Atlas -
