NGC 6754 is a barred spiral galaxy in the constellation of Telescopium. Its velocity with respect to the cosmic microwave background is 3176 ± 11 km/s, which corresponds to a Hubble distance of 152.8 ± 10.7 Mly (46.84 ± 3.29 Mpc). Additionally, 10 non-redshift measurements give a distance of 137.15 ± 4.19 Mly (42.05 ± 1.285 Mpc). It was discovered by British astronomer John Herschel on 8 July 1834.
According to the SIMBAD database, NGC 6754 is an Active Galaxy Nucleus Candidate, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.
