 Few places in the sky are more inspiring than in Leo, with numerous galaxy clusters and bright groupings. This pair is one of the most spectacular, and rich with detail. The seeing this night was terrible, and even a mild deconvolution made for poor star images. None the less I decided to go for the faint detail and blue arms of these two galaxies with the increased blue sensitivity of our new camera.

Two images are presented here, on the left a standard deep image processed normally. On the right is a highly stretched image to show the huge outer envelope of stars surrounding M66.

On the left is M65, a 10.3 magnitude nearly edge on spiral that is a huge 9.8 arcminutes in size. Brownish red dust lanes and a sunshine yellow core bring it to life. On the right is M66, an inclined spiral that is even brighter at 9.7 magnitude, and also a huge 9 arcminutes long. Only M66 seems to display a bright stellar core, the area around M65's core is filled with a yellow glow of billions of suns. A few 18th magnitude background galaxies are present, but require a map to locate. South is up in this representation.
