Chicago · Bortle 9 · Rooftop

I image deep space from a Chicago rooftop.

Deep sky astrophotography from one rooftop in Chicago, under some of the most light-polluted skies on earth. Every frame here was shot from that same roof, straight through the city glow.

The Mission

Capturing the cosmos from the city.

I'm Brett Horin, a hobbyist astrophotographer shooting deep sky objects from my Chicago rooftop — a Bortle 9 sky above one of America's most light-polluted cities. Everything here was captured from that one roof, in the middle of the city.

My work is built on one idea: you can do serious deep sky imaging without leaving the city.

Brett Horin, Chicago
