Galaxies

Shooting of the last day of the year without auto-guider. The subject is a peculiar couple of objects: at the top left the Surfboard Galaxy and at the bottom right the Owl Nebula. This galaxy is a barred spiral one, but its shape is difficult to see as the galaxy is edge-on. Opening the picture and enlarging it, you can see a multitude of galaxies in the background at various distances from us. M108 is less than 50 million light-years away.

A picture of the triplet made with the Nikon D750 and the C8 in prime-focus mode. Images were calibrated only with the flat frame without the dark ones. The different structures and colors of this group make it a very scenic subject. The image was taken from home in the pre-exam period and therefore it was rediscovered and elaborated many months later. I love the result, considering that the frames were not guided

M81 and M82 are the two brightest components of a group of galaxies located in the constellation of Ursa Major, which takes the name of Group of M81. In this image the only visible galaxies of this cluster are the two main ones (M81 on the right, M82 on the left) in addition to Holmberg IX, an irregular dwarf galaxy satellite of M81, like the Magellanic clouds for the Milky Way. This small galaxy is visible below M81 as a whitish spot that almost merges with the background noise. The structures visible in the two galaxies are spectacular. The shooting was carried out with a variable temperature between -2 ° C and -4 ° C and conditions that were not perfect due to the presence of snow on the ground.

Within the constellation of Perseus it is possible to see this imposing cluster of galaxies. The Perseus Cluster is a peculiar object as it contains more than a thousand galaxies inside. NGC 1275, the brightest galaxy visible in the photo is also an X-ray source due to the supermassive black hole situated in the galaxy.

NGC 7331 is a spiral galaxy in the constellation of Pegasus and is the largest in the group of galaxies that takes its name and which includes the three other galaxies visible below the main one. Unlike most spiral galaxies, NGC 7331's core rotates opposite to the disk

This spiral galaxy in Canes Venatici is so inclined that it shows many structures of its arms, rich in HII regions. I have two versions of this image: one has the luminance channel only, the other is a two-color version with the H-alpha signal added in the red channel.

The particular shape of NGC660 is probably due to the collision between two galaxies. It is a lenticular galaxy surrounded by a disc of stars inclined at 45 ° with respect to the central part

M96 is a particular spiral galaxy: the central body is surrounded by a faint halo extending for more than 100,000 light years composed of young stars and many others in formation.

This brilliant edge-on spiral galaxy in Andromeda shows us a spectacular dark lane of gas and dust
