After several months of image processing practice, this capture had been really calling out to me to try again. So much happier this time around!
Located about 2,900 lightyears away in the constellation Cepheus, NGC 7822 is a star-forming complex sometimes referred to as the “Question Mark” or “Teddy Bear” nebula. I love capturing these stellar nurseries due to their dramatic areas of density that help create such dynamic and interesting images. NGC 7822 even features “elephant trunks” similar to the famous Pillars of Creation.
