NGC 4725 is a 9.3 mag barred spiral galaxy (and Seyfert 2 galaxy). While most spiral galaxies, including our Milky Way, have two or more spiral arms, NGC 4725 has only one. The galaxy has opaque dustballs and a yellowish central beam consisting of an older star population. NGC 4725 has a diameter of more than 100,000 light years and is 41 million light years away in the constellation Coma Berenices. In the picture field, a traditional-looking spiral is also seen as a smaller background galaxy (NGC 4712) - in addition, NGC 4747 with a pronounced tidal tail. NGC 4725 was discovered on 10 April 1785 by the German-British astronomer Wilhelm Herschel.
The image was exposed in a period of one year. The implementation also involved a small part of the FSQ85, which has a much larger field.
