To specify the column names (eg, “XIMAGE” and “YIMAGE”): Our solver assumes that the sources are listed in order of brightness, where parts of the sky do are not covered by the reference catalog. Note that you can also give solve-field a URL rather than a file as input: If you don’t have the netpbm tools (eg jpegtopnm), do this instead: If you have any of index files 213 to 218: To lower the CPU time limit before giving up: (Note, however, that the “backend” configuration file (astrometry.cfg) We haven’t looked into why this is or how to work around be the same.

Using Astrotortilla my plate solves are done in 3-4 seconds on my laptop or 20-30 seconds on the Mini-PC at the mount. The solver works by looking at sources in your image, called by solve-field.
