The main subjects in this photo are Mars (slightly left of center toward the top of the photo) and the Pleiades (slightly right of center toward the bottom of the photo).

I shot four 30-second exposures with my iPhone 14 Pro and a small tripod.

I lightly edited each of the four exposures for light and dark colors and noise reduction in Adobe Lightroom. Then, I manually stacked the four exposures in Adobe Photoshop.
