Image Description and Details: Well-known and frequently photographed object – the center of the “Question Mark” nebula, SH2-171 or NGC 7822, located in the constellation Cepheus.

I aimed to strongly highlight and emphasize the dark dust structures, as there’s a lot happening there. It’s an opportunity to bring out some intricate details that are not always visible in every photo of this region of the sky.
