Description
This image is a comparison of photographing the same portion of the Milky Way from suburbia (Whitley Bay, Tyneside) and in the country (Rookhope, North Pennines). This is the Cygnus area; the bright star on the right just above centre is Vega. Part of the problem in suburbia is that you cannot take exposures as long as you can in the country without the detector saturating. The photo on the right is a stack of 32second exposures at ISO 6400 but on the left only 10seconds at ISO1600 was possible for each individual exposure.
