The M66 group, otherwise known as the Leo Triplet, is in the constellation Leo and is a group of spiral galaxies.

It lies roughly 35 million Light-years from Earth and contains Messier 65, Messier 66, and NGC 3628.

All three galaxies have been affected by gravitational interactions with one another.

This image was taken back in February with my old one-shot color camera, The ZWO ASI533MC-Pro and Optolong L-Pro filter to block out unwanted light pollution.

This was a total of 3.5 hours of image integration taken from my backyard in Johnston.
