ZEITREISE font / Header Slider / logo

Hi there,

I just bought the theme ZEITREISE.

About the header Slider area:

1- I can not put my logo in the center of this Header Slider …. when I load my logo, it appears very small, justified left. It is hardly visible ….
2- Can you let me know the name of the font used on the slide title?

I am a little surprised and disappointed by the complexity of installation of this new theme, without demo video to proceed with the installation … .

Best, Marion
