Description

HCG 92, also known as Stephan's Quintet, is a compact group of galaxies located in the constellation Pegasus.

I imaged this group of very small galaxies from a Bortle 4 zone, and made sure to frame my shot so that a much larger object, NGC 7331would also be visible in the final image!

Stephan's Quintet is a visual group of five galaxies that appear to be very close to each other. Scientists confirmed that at least four out of the five objects are so close to one another that they are interacting. These four members (HCG 92) are bound by gravity and will merge into one large galaxy in several million years. As for the fifth galaxy visible, it only appears to be close to the group but is actually much, much closer to Earth (39 million light years) than the other four (260-340 million light years).
