Structure is what deep-sky observing is all about. Hunting faint little galaxies all night is a challenge and can be rewarding. But there is nothing quite like an observing session with a galaxy that looks like a galaxy. Seeing spiral arms, a dark lane through the disk, and HII regions of new star formation transform an object from a misty glow into a stellar metropolis: a galaxy. NGC 7479 looks like a galaxy. You'll find it 3 degrees due south of 2.5 magnitude Markab, the star at the southeast corner of the Great Square of Pegasus. An alternate route would be to start at 4.2 magnitude Xi (46) Pegasi and slew 4.5 degrees due east. Either way, you will run right into NGC 7479
