I think this is my best one this year. CSC said 4/5 seeing; that seemed about right.

M95 and M96 are a fine pair of galaxies in Leo separated by a mere 42' and can be seen together in the same field with binoculars and telescopes under low magnification. Both are spiral galaxies with M96 being the brighter of the two. M95 has a bright core surrounded by a granular halo. In dark skies M95 might reveal hints of spiral structure and a bar extending from its centre region. Also nearby is the elliptical galaxy M105. Together, M95, M96 and M105 form the Leo Galaxy Group. The Hubble Space Telescope recently measured the distance to M95 using Cepheid variable stars, and used this distance measurement as one of the pieces of data in a new measurement of the age of the universe. The results of this study indicate that the universe is about 14 billion years old.

M81 and M82 are perhaps the most famous pair of galaxies in the sky and both can be seen in the same low magnification field of view. Both are spiral galaxies but M81 is nearly face on, while M82 is edge on. The contrast offered by these two galaxies is one of the visual delights of the night sky. M81 and M82 are separated by only 150 000 light years. Tens of millions of years ago, the larger (and ten times as massive) M81 passed close by its smaller neighbour, inducing a round of starburst formation in M82. It also led to the birth of over 100 globular clusters, and disrupted the appearance of M82, so much that it is sometimes classed as an irregular galaxy instead of a spiral galaxy. While quite faint in visible light, M82 is the brightest galaxy in the sky in the infrared region.
