The Center of the Galaxy
4

The center of the Galaxy seen from the Sierra de San Pedro Mártir in Baja California. The Sierra is one of the darkest professional astronomical sites in the world; when there is no moon, the sky is light and the Earth is dark.

This is a stack of 16 images each of 15 second at f/4 aligned and combined with Starry Landscape Stacker. So, effectively, it's a 15 second exposure at f/1. Pretty cool that a $40 program can turn your slow kit lens into an f/1 lens.

This is my first attempt with this program. Next time, I'd probably shoot 64 images each of 8 seconds at f/5.6; that would maintain the overall exposure but reduce trailing and coma.

Regards,

Alan
