Understanding Light Pollution and the Bortle Scale
Light pollution creates a veil that obscures the night sky’s most spectacular features, directly affecting what you can capture in your astrophotography.
The Bortle Scale, ranging from Class 1 (pristine dark skies) to Class 9 (inner-city brightness), helps you evaluate potential shooting locations based on sky darkness.
Understanding where your location falls on this scale lets you set realistic expectations for your images and plan accordingly for the celestial objects you hope to photograph.
Light Pollution Impact
As photographers venture into the night to capture celestial wonders, they quickly discover that not all dark skies are created equal.
Light pollution has dramatically increased over the last century, with 80% of people worldwide now living under light-polluted skies, making truly dark sky areas increasingly rare and valuable.
When you’re planning your Milky Way photography session, understanding light pollution’s impact helps you determine if a location is dark enough for your goals:
- Bortle 1-2 locations offer pristine views with minimal light interference—ideal for capturing detailed celestial objects
- Bortle 4 areas provide accessible options while still delivering good imaging possibilities
- Sky quality meter readings help quantify darkness levels, ensuring night photographers don’t waste time in unsuitable locations
Bortle Scale Basics
Created by astronomer John Bortle in 2001, the Bortle Scale provides photographers with an essential framework for understanding the darkness potential of any location.
This nine-level classification system measures night sky quality, with Bortle 1 representing the darkest possible skies and Bortle 9 indicating severely light-polluted urban areas.
When planning your night photography sessions, knowing the Bortle classification of your shooting location is vital.
Bortle 2-3 areas offer excellent visibility of the Milky Way and other celestial objects, while Bortle 4 locations—typically found within a couple hours of cities—still provide workable conditions for decent astrophotography.
As you move up the scale, light pollution increasingly obscures fainter stars and astronomical features.
For serious night sky photography, seek out dark skies rated Bortle 3 or lower.
