I came across a nice algorythm for exoplanet autoguiding on Python. It looks like fairly simple (It seems like the aligment module) and it is giving good results in case of seeing issues during the sesion like faint clounds passing. I would like it to be implemented in Ekos autoguiding but I a m not a programmer.
I hope this will be useful for astrophotography and exoplanet transits. Here is the github page:
