History

This galaxy was discovered by William Herschel on 9 December 1798 using his 18.7 inch reflector. He cataloged it as I 281 and noted: «Considerably bright, extended, north preceding, south following, having a nucleus in the middle, 6' long, 1.5' broad.» [465] Dreyer added the galaxy as NGC 613 to his «New General Catalogue» published in 1888.

Finder Chart

The galaxy NGC 613 lies in the constellation Sculptor deep in the south at a declination of about -29° nearby the 5.6 mag star τ Scl. This forms a horizontal chain with three other stars of seventh to eighth magnitude, which is conspicuous in a wide-field eyepiece with a field of view of at least 1°. North of it lies the galaxy. The best viewing time is September to November when it is highest above the southern horizon.
