Quote from the Deep Sky Field Guide to Uranometria 2000:
Very small, extremely bright nucleus.
Quote describing NGC 4725 from A.Sandage’s The Hubble Atlas Of Galaxies:
This is a transition galaxy between a normal Spiral and a Barred Spiral. The region of enhanced luminosity across the central lens is not a well defined bar........ The internal "ring" is not complete but resembles that in NGC 4580. It begins abruptly at the edge of the amorphous central region and breaks into multiple, tightly wound spiral arms in the southeast quadrant. The dust lanes are seen silhouetted against the background light especially well in this quadrant. The inner arms are resolved into knots. Two faint external arms are present...... These arms are smooth in texture with no hint of resolution into knots. The external arms are not on opposite sides of the nucleus but travel together, one lapped on the inside of the other.......
