Background

M104 is the Sombrero Galaxy — an edge-on lenticular/spiral galaxy  30 million light-years away in Virgo. Famous for its prominent dark dust lane bisecting a bright bulbous central bulge, giving it the visual appearance of a wide-brimmed hat. One of the most photogenic galaxies in the sky.

My Observing Notes

25-cm (Meade 10-inch LX200, The Coffee Grinder): Bright bulbous core clearly visible, with the characteristic dark band of dust running through the length of the galaxy.(Friday, April 2025)
