This is the photograph that truly got me hooked on astrophotography. It was taken in early February 2018.

It was captured, as they say, "on a whim." I didn't have my own camera back then; I was shooting with an acquaintance named Nikolai, a big fan of experimenting with exposure time and ISO.

In short, this is a mix of frames with exposures from 1 second to 25 seconds and ISO from 400 to 6400. Most, however, are 15 seconds at ISO 4000.

Minimal processing: DSS and a little bit of FS.
