About this image

This faint (mag 14.4, 13.7) pair of lenticular galaxies was discovered by Ormond Stone in December 1885. He was using a 26.25" refractor at Leander McCormick Observatory, Charlottesville, Virginia.

NGC 1505 is the larger of the two with a diameter of c.155,000ly - NGC 1504 c.95,000ly. The galaxies are about 440million ly away, and are separated by perhaps as little as a few hundred thousand ly. Their common recessional velocities suggest they are a physical pair.

A number of other fuzzy objects can also be seen in this PIRATE image.
