NGC 891 is a spiral galaxy viewed from the edge in the constellation Andromeda; it is also possible to observe the lane of dark dust that crosses it in half.
M 33 or NGC 598 is a spiral galaxy in the constellation of the Triangle; it is relatively close to us and its apparent size is greater than that of the Moon, but it is almost impossible to see it with the naked eye due to its low brightness.
M 100 or NGC 4321 is a spiral galaxy of the Virgo cluster at 55 milion of light years from us.
In the photo near to M 100 you can see NGC 4323 and NGC 4328 that are two satellite galaxies of M 100 as highlighted in the second photo.
M 66 is a galaxy in the Leo constellation and it is a spiral galaxy with a weak bar.
It is located at a distance of 31 million light years and is moving away from us with a speed of about 700 km/s.
This is my first attempt to photograph a galaxy, the subject is the spiral galaxy M 51 interacting with the galaxy NGC 5195.
