NGC/IC Objects

NGC 7597 & Co.: Galaxy Cluster (Pegasus) RA: 23h 18.5m / DEC: +18° 41'.4
Instrument: 18-inch Obsession

Pegasus, the winged horse, is where you'll find this fine collection of galaxies. My sketch captures a 199X view in the 18-inch Obsession. The brightest member of the quartet, NGC 7597, is nearly centered. This 14th magnitude galaxy covers a 40" diameter patch of sky and is even in brightness. Like the other galaxies in this field, NGC 7597 has a radial velocity and redshift suggesting a distance of between 550 million and 600 million light-years. 15th magnitude NGC 7602 is seen about 3' to the east. It's tiny at just 20" in size and a 14th magnitude star glows dimly to the north. 8.0 magnitude HD 219818 is the brightest star in the field and shines 3' south of NGC 7602. NGC 7598 is spotted about 4' north-northwest of NGC 7602. It's a 15th magnitude stellar burg, about 20" in size with a faint star immediately to the southwest. A 9.8 magnitude star simmers 2' to the west-southwest. The bright pair near the western field boundary are 8.8 magnitude HD 219713 (farthest west) and--3' to the northeast--9.0 magnitude HD 219726. Looking 2' northwest from HD 219726, the 15th magnitude glow of NGC 7588 is pulled from the night sky. This 30" by 20" oval is aligned roughly east to west. Some 40 stars dot the field. The tightly-grouped galaxy cluster Hickson 94 lies just beyond the field of view to the west.
