(Get the code!)
Just to check: If one changes the DeltaT formula in Stellarium, it looks Stellarium uses the TT as its basis. So it calculates UT (using TT-DeltaT). So the presented (UT) time changes in the time window of Stellarium.
If I go back to the same UT (after changing the DeltaT formula) I see the same sky (I did not compare it dot for dot, but they look quite the same). But lets first see if you see the same as me.
It took me also some time to understand the changing of the view. I don't know what is better keeping TT the same or UT. I think for the average user; keeping UT the same sound better (keeping TT the same is more for the expert). But not sure: Stellarium is the only programme that has this diversity of DeltaT formula, so comparing with other programmes is difficult.
All the best,
Victor
