Register images to az/el using the astrometry.net program
Project description
Azimuth/Elevation converter for Astrometry.net
Note: If you want to work with the intermediate steps (source extraction) or photometry, see my AstroPy-based examples.
Prerequisites
Astrometry.net 0.67 or newer
or, use the astrometry.net cloud service–handy for Windows users
Installation
python -m pip install -e .
Astrometry.net index files
If you use astrometry.net on your PC, you may need to install the index files and setup your config file to point at them:
sudo ./get_data.sh
Command line options
- --h5
write az/el et al to HDF5
- --mat
write az/el et al to .mat Matlab save file
- --png
write az/el et al to PNG
- -h
to see all the options you can use
Examples
Astrometry.net installed on your PC:
python PlateScaleFITS.py myimg.fits -c 61.2 -149.9 -t 2013-04-02T12:03:23Z --h5 --png
gives HDF5 .h5 with az/el ra/dec and PNG plots of the data. Both files contain the same data, just for your convenience.
The 61.2 -149.9 is your WGS84 coordinates, 2013-04-02T12:03:23Z is UTC time of the picture.
wcs.fits from the Astrometry.net WEBSITE:
first rename wcs.fits to myimg.wcs:
python PlateScaleFITS.py myimg.wcs -c 61.2 -149.9 -t 2013-04-02T12:03:23Z --h5 --png
