Juan Carlos Casado made a timelapse video of the Southern Cross as seen from the Teide National Park in Tenerife at 2300 metres high. This small constellation is only visible briefly above the horizon every day from Spanish soil thanks to the atmospheric refraction. But in Celestia you just cannot duplicate that: Acrux keeps under the horizon no matter what.

Can anyone make sure its refraction model is working well?
