No, no se ve asi... es un fake... no se ve mas que lo que se ve en un desierto o en el mar lejos de fuentes luminicas. La atmosfera impacta poco... Eso es una composiciin de imagenes de larga exposicion... solo hay que ver las fotografias de las misiones Apolo desde la luna para hacerse una idea

The Seestar app has the "plan" option. You can select more than one target and select the photo starting and ending time for each one. I don't know if you refer to this app...
