    An extremely rare clear, Moonless night last night and I managed to get 11 x 15-minute subs on NGC 7822 using the 2 x Canon 200mm prime lenses and the 2 x Trius M26C OSC CCDs. Came out way better than I was expecting for only 11 subs. Greg

    Well out of practice with both capture and processing but better than the last few months of nothing. Object:NGC 3201 Object Info: NGC 3201 (also known as Caldwell 79) is a low galactic latitude globular cluster in the southern constellation of Vela. It has a very low central concentration of stars. This cluster was discovered by James Dunlop on May 28, 1826 and listed it in his 1827 catalogue. He described it as "a pretty large pretty bright round nebula, 4′ or 5′ diameter, very gradually condensed towards the centre, easily resolved into stars; the figure is rather irregular, and the stars are considerably scattered on the south". The radial velocity of this cluster is unusually high at 490 km/s, larger than any other cluster known. This corresponds to a peculiar velocity of 240 km/s. While high, this is lower than the escape velocity of the Milky Way galaxy.[10] It is located at a distance of 16,300 light years from the Sun and has an estimated 254,000 times the mass of the Sun. This cluster is about 10.24 billion years old. The stellar population of this cluster is inhomogeneous, varying with distance from the core. The effective temperature of the stars shows an increase with greater distance, with the redder and cooler stars tending to be located closer to the core. As of 2010, is one of only two clusters (including Messier 4) that shows a definite inhomogeneous population.
