The Bortle Scale
How Bortle class affects astrophotography
In terms of backyard astrophotography, the sky quality will
have a huge impact on your images. Deep-sky imaging
under a bright city sky means that you’ll have to put a lot
more exposure time into your projects than someone in a
rural location
You’ll need to work harder to improve the signal-to-noise
ratio of your final image because the signal (light emitted
from the object) is buried underneath a layer of light
pollution
To help capture images with improved contrast and less
background skyglow, light pollution filters that isolate
specific wavelengths of light can be used
