The spiral galaxies M65, M66 and NGC 3628 represent a very well known small group of galaxies in the constellation of Leo. Because of the different orientation to Earth, only M65 and M66 reveal the spiral arms to a terrestrial observation, while NGC 3628 shows its typical “hamburger” shape. A plum of dust extends from the outer edge of the galaxy.
The group is imaged in broadband LRGB integration (4.5h L, 2h R/G/B each) with the addition of 1.5h Ha to enhance the HII emission regions.
