Not the galaxy NGC 7497 is the champion of this image but the "galactic cirrus", dust and molecular clouds between the stars and above the galactic disc. They don't glow by themselves but reflect the integrated light of the stars of our galaxy, therefore also called "Integrated Flux Nebula".
In the constellation Pegasus several objects can be imaged together with these nebulous structures, like the globular cluster M15.
