The Grus Quartet of Galaxies

Image Description:
Here reveals only three of its four members in the constellation of The Crane.
Located about 60,000,000 light-years from Earth, this beautiful group of spiral galaxies is gravitationally bound.
​At top-right is NGC 7582, a Seyfert Type-2 galaxy, exhibiting lots of star birth. At left is NGC 7599, with NGC 7590 at center.
The missing member of the quartet is NGC 7552, which is another 'starburst' galaxy. The elliptical galaxy, PGC 71043 is at 6 o'clock.
Many thanks to my collaborator and friend, Mike Selby, who acquired and calibrated this fine data from Observatorio El Sauce, Chile.
