I would like to submit a feature request.
Indeed, maybe some of you know NINA. It has a exoplanet plugin very cool. This plugin shows exoplanet ephemeris and it is then easy to schedule which transit we want to record.
With the developer of this plugin we have defined a file output that will be used in Siril. This file contains the coordinates of the target (i,e, the exoplanet) and other stars that can be used for reference.
With this file, it is possible to produce a light curve in (almost) one click and no effort.
I attached the file and a video showing how Siril will use the file (in its 1.2.0 version).
