The galaxy NGC3628, nicknamed the Hamburger Galaxy, is a large, pale galaxy seen from the side. She is part of the Lion triplets with M66 and M65. Although it is larger, it is less bright and more difficult to observe in a small telescope than the other two. It has a special shape caused by the gravitational interaction with its two other neighboring galaxies. Its profile is marked by a dark band of gas and dust especially visible in front of the nucleus. It's a beautiful galaxy to image. |
