Notes

The Sombrero Galaxy was discovered by Pierre Mechain in May 1781. Lying at a distance of about 50 million light years, this galaxy has a span of about 100,000 light years along its major axis. It is one of the brightest and most massive of galaxies in the Virgo Group.

High winds aloft resulted in poor seeing on the night this image was captured, hence the lack of detail in the equatorial dust lane and interior of the galaxy.
