Nachthimmel vs Himmel
sky / heaven
'der Himmel' and 'der Nachthimmel' both refer to the space above us that we can see. 'Himmel' is more general and fits any time of day: morning, daytime, evening, or night. 'Nachthimmel' is more precise and means only the sky at night, often with stars, the moon, or planets. Learners may confuse the words because the night sky is also a sky. If the night is important or you are describing stars, 'Nachthimmel' is more precise. Otherwise, 'Himmel' is usually enough.
Nachthimmel
Auf dem Land kann man am Nachthimmel besonders viele Sterne erkennen.

Himmel
