Wordpress Astrometry.net Plugin
Welcome to my first Wordpress Plugin. It is an Plugin, that provides a Gutenberg block, which uses astrometry.net for solving an astronomical image.
What it does
- Solving astronomic images via astrometry.NET
- Colored annotations by different catalogues (HD, Bright, NGC, IC, the ones, which are delivered by astrometry.net)
- Globally turn on Messier Objects to override NGC
- Global settings administration page: Decide wether to show the celestial grid or not. Choose colors of catalogues and grid
- All annotations are stylable via custom CSS as they are SVG objects
- Image zoom / monochrome-invert switch
- Zoomable skyplot
- Astrometry data output (RA,Dec,Field) and photografic details output (frames, exposuretime, date, equipment) below image
- Extended wordpress search (Tags like M101 are stored in customfields)
- Default localisation is english, a german localisation is also included
