The galaxy NGC4565 in Coma Berenices

Image: NGC4565, NGC4562 and other galaxies

NGC4565, an edge-on galaxy in the Coma Berenices constellation, is several times brighter than the Milky Way. It looks like the Sombrero Galaxy and NGC891 in our firmament. NGC4565 has an apparent size of 16"x2.2" and due to its distance of 50'000'000 light years from us, a diameter of 100'000 light years is assumed. Recently, a small black hole has been detected in its centre. NGC4565 is observable even with moderate amateur telescopes under darks skies.
