Mano Prieto Observatory



Object: M64
Constellation: Coma Berenices
Distance: 13.5 million light-years
Magnitude: 8.5

M64, also known as the Black Eye Galaxy, owing to the dense dust lanes near the core, and appearing as such in the eyepiece, is approximately 13.5 million light-years distant in the Constellation Coma Berenices. The main core of the black dust cloud is thought to be about 40,000 light-years in diameter, and rotates opposite the inner regions of the galaxy nearer the core, brought on apparently by the absorption of a satellite galaxy, and bringing about heavy star formation activity within the obscurring cloud.
