IC 1148 = NGC 6020. IC 1148 is another of the about 100 nebulae found by T. H. Safford at Dearborn in the mid-1860s. It, and the other 51 nebulae not found previously by other observers, was first listed in an appendix to the NGC. It's approximate position is only about 15 seconds west of NGC 6020 -- there is nothing in Safford's place -- and his brief description ("neb. *") is appropriate for the galaxy. The galaxy was found again about a decade later by Stephan who provided a micrometric measurement of its position.
