Astrometry.net is easy to use on Linux and Windows.Windows uses Windows Subsytem for Linux for Astrometry.net.
There are three options for using the Astrometry.net software: Images can be calibrated through a user-friendly web service, on the flickr photo-sharing site, or by a downloadable software package for the computer-savvy. Definition of astrometry: a branch of astronomy that deals with measurements (as of positions and movements) of celestial bodies Other Words from astrometry Example Sentences Learn More about astrometry Other Words from astrometry. Astrometry is the science (and art!) of precision measurement of stars' locations in the sky. When planet hunters use astrometry, they look for a minute but regular wobble in a star's position compared to the positions of other stars. Apr 14, 2021 Ask the astrometry help desk.

The major steps in achieving a useful WCS starfield polynomial fit are:
- source extraction (identifying star position in image frame)
- quad asterism hashing, including tolerance for star position wiggling due to noise.
- Match hash to star catalog, at least 3 choices are available:
- USNO-B
- 2MASS (longwave infrared)
- Bayesian decision process, find extremely high probability solution or reject.

Notes
[Optional] compile
This is normally not necessary, unless you want to customize/optimize.
Prereqs:
Install: If you have Anaconda/Miniconda Python as your default, Astrometry.net will use them (or whatever your default Python is).Back to at least Astrometry.net 0.70, Astrometry.net is Python 3 compatible.
