# Fchart3

Fchart3 is a Python project designed to create high-quality astronomical charts using data from Stellarium, Kstars, and HnSky, including 300 million stars. It can generate both offline charts with output to PDF and online interactive charts, as demonstrated in the **CzSky** project.

Online interactive version available on project **CzSky**:
- [CzSky Chart](https://www.czsky.eu/chart?ra=1.532197702857378&dec=0.06961660554646551&fsz=100&splitview=true)

## Install

Download this project and run: 

`python setup.py install`

### Run
To see command-line options, use:
`fchart3 --help`

Generate findchart for Crab Nebula:
`fchart3 M1`

Generate complex chart of M39 (m39.pdf) region:
`fchart3 -width 190 -height 270 -fieldsize 40 -limstar 9 -limdso 9 --show-nebula-outlines --show-enhanced-milky-way --font-style-bayer bold --font-style-dso italic --flamsteed-numbers-only --show-equatorial-grid --hide-map-orientation-legend --hide-map-scale-legend m39`

Generate complex chart for M39 (m39.tikz) region with output to TIKZ format.
`fchart3 -f m39.tikz -width 190 -height 270 -fieldsize 40 -limstar 9 -limdso 9 --show-nebula-outlines --show-enhanced-milky-way --font-style-bayer bold --font-style-dso italic --flamsteed-numbers-only --show-equatorial-grid --hide-map-orientation-legend --hide-map-scale-legend m39`
