Description

NGC 6791 is an open star cluster in the Lyra constellation. It was discovered by Friedrich August Theodor Winnecke in 1853. At roughly 8 billion years old, and with an Iron to Hydrogen abundance ratio that is more than twice that of the Sun, it is one of the oldest and most metal-rich clusters in the Milky Way. This is contrary to the typical rule-of-thumb where older means more metal-poor. Compounded with the fact that it has an unusually high population of stars, NGC 6791 is among the most studied clusters in the sky.

I take this one near dawn with moon just rising and Lyra high enough up for possible good image. Other requirement is nice star field and this one certainly is that indeed! RGB 3 x 300 seconds each.

Really pleased how turned out.
