NGC 525, also occasionally referred to as PGC 5232 or UGC 972, is a lenticular galaxy located approximately 95.6 million light-years from the Solar System[4] in the constellation Pisces.

As he also noted the mag 11-12 star just 2' northwest, his position is fairly accurate.

[6] The galaxy was later catalogued by John Louis Emil Dreyer in the New General Catalogue, where it was described as "very faint, very small, 11th or 12th magnitude star 5 seconds of time to west".

[5] The galaxy appears very dim in the sky as it only has an apparent visual magnitude of 13.3 and thus can only be observed with telescopes.

[2] The object's distance of roughly 95.6 million light-years from the Solar System can be estimated using its redshift and Hubble's law.
