Another reason to make J2000 coordinates an (explicit) option in the alignment module is that the astrometry.net index files are keyed to J2000 and the WDS coordinates written to the FITS headers are therefore also J2000. And though other catalogs are available, astrometry.net is the system documented in the Ekos tutorial.

Or maybe coordinate conversion between systems could be a separate entry?

Or am I missing an option somewhere? The INDI written headers include the equinox as a separate field, indicating, perhaps, that it can be changed.
