Hello

Dahl Field Notes is a backyard astronomy log run by Gabriel Dahl in Porto. Dark adaptation takes twenty minutes and one bright screen to ruin. It is not glamorous, but it holds up. Most problems with light pollution turn out to be problems with time.

This site started in 2025. The best advice I got was just to slow down. This began as a quick note and bit by bit turned into something longer.
