NGC 3628, also known as Sarah's Galaxy (though I don't know why) or, more prosaically, The Hamburger Galaxy, is one the Leo Triplet of galaxies, the other two being M65 and M66. Unlike the other two, which Messier spotted, NGC 3628 was discovered by William Herschel in 1784. The galaxy is 35 million light-years away. The galaxy, seen edge on features a broad lane of dust which obscures the central regions. This dust lane, like much of the galaxy itself, has an unusual shape and indicates some significant gravitational disturbance. In fact the galaxy seems to be interacting gravitationally with the other two members of the triplet, and further evidence of this is a very long tidal tail, which is not visible in this image. 

This is the first processed image with the then-new Officina Stellare Ultra-Corrected RC360 at Le Bourdieu observatory. There was still quite a lot of collimation and other adjustments needed!
