Our version of the Deer Lick Group & the Stephan Quinteta with the whole AstroFleet team. The data were acquired with our setup (TS-Optics CF-APO 155mm & ASI2600MM Pro) hosted at PixelSkies, Spain plus a Newton 250 hosted in Ariège, France!
Located in the constellation Pegasus, two groups of galaxies are visible in this image:
However, only the first four galaxies mentioned (from NGC 7317 to NGC 7319) form a compact group and are located in the same region, with their spiral arms and disks being significantly distorted by tidal forces.
This group is estimated to be situated approximately 340 million light-years away from the Milky Way. NGC 7320, on the other hand, is much closer (between 35 and 40 million light-years).
It is also noteworthy that numerous Integrated Flux Nebulae (IFN) are present in the image.
