Neither. It is what I call a "blend" by which I mean that all photos were taken over about a 10 minute period with the camera fixed on the tripod. The sky is about 25 short exposures, stacked in Sequator (free software) for noise reduction and to align stars. The foreground is a separate set of about 5 exposures using light painting with a hand torch, with lower ISO and adjusted focus and then blended in GIMP using the lighten mode.
I use the word composite to refer to images taken in different places or times and combined in postpro - but that's possibly just me - and could open up a whole can of worms and opinions
