NGC4565 & NGC4562
NGC4565, an edge-on galaxy, 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 our galaxy, 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.
Exposure: L=5x300s, RGB=3x300s each channel, focal length 660mm (f/5.2), pixel size 5.4μ. The heavy light pollution caused by the city lights was completely removed with filtering and photo processing techniques.
