The Leo Triplet, or the M66 Group, is a group of interacting spiral galaxies located in the constellation Leo. The group consists of the galaxies M 65, M 66 and NGC 3628, also known as the Hamburger Galaxy.
The Leo Triplet lies at appr. 35 million light-years from Earth.
The 3 galaxies have all been affected by gravitational interactions with each other. This is evident in the deformed, drawn out spiral arms of M66 that are experiencing a high rate of star forming activity and in the warped, inflated disk of NGC 3628. With a prominent tidal tail consisting mainly of young blue stars, NGC 3628 seems to be the most affected of the three, while M65 appears to have suffered the least damage from the interaction.

The Veil Nebula, a supernova remnant, is a cloud of heated and ionized gas and dust in the constellation Cygnus. The source supernova was a star 20 times more massive than the Sun which exploded between 10,000 and 20,000 years ago.

This is my first moonshot. And I am very glad with the result! The Olympus OM-D E-M1 was directly connected to my new (but old) 135/720mm telescope (focal projection). I took 10 shots at ISO 200 1/400sec. and stacked the best 5 with Registax6. The software runs on an imac under wine and it was a real learning curve to succeed. Finally a 16bit .png file was imported to Lightroom for a little CA correction, noise reduction and sharpening. N.B. astronomers call this lunar phase "first quarter".
