NGC7331 is a magnificent Galaxy in the constellation Pegasus. The galaxy shows a very bright compact core and spiral arms with many patches of dust and gas. The spiral arms spread out fairly far but get very dim. Right to the east of the Galaxy three much smaller ones are seen. From top to bottom: NGC7336, NGC 7335 and NGC 7337. Several other galaxys can be spotted in the field of view.
Just outside of the field of view to the South-West there lays the famous Stephan's Quintet.
NGC7331 was discovered by William herschel in 1784. he described the galaxy as very bright and considerably brighter in the center. He also noted it's larger and very extended.
