I have imaged NGC4565 already here and here, but on last Zatom astroparty I took a look onto this galaxy and could not resist to picture is again with 10″ telescope. Needle Galaxy is a kind of monster – it is more luminous than the Andromeda Galaxy. It has two satellite galaxies, and also about 240 globular clusters were found there. NGC4565 is one of the brightest members of Coma I Group. The transparency was decent, so I was able to capture some faint outskirts despite modest 200 minutes of luminance. But the seeing was so-so. I estimate I need about 3 times more of data at similar conditions to reveal some nice features in Needle Galaxy. At my suburban imaging location.
NGC4565 was discovered by William Herschel in 1785, and is called Needle Galaxy due to its apparent shape. It is classic edge-on spiral, one of the most spectacular galaxies. It lies about 40 million light years away. I caught photons for this image in April 2018. Conditions were decent, though I have some problems with colour balancing of the final image. Some dust lane details have been resolved. You can also notice, that disk structure shows warping at its edges due to an ancient interaction with passing galaxy.
