Object name: NGC6811

Designation(s): NGC6811,

NGC 6811 is an open cluster, type IV3p, in Cygnus. WEBDA puts its distance as 1,215 parsecs (~ 4,000 light-years) and estimates its age as about 630 million years. Other sources ( put its age at about 1 billion years and distance at 3600 light-years. Dreyer's NGC description says it is large, pretty rich, little condensed with stars ranging from 11 to 14 magnitude. Its diameter is listed at 15 minutes which isn't all that large. Those I'd consider large won't fit into my field of view. It is one of four open clusters that are within Kepler's planetary search field of view. I find a lot of papers looking at the variability of its red giants but didn't find any mention of possible planets being found. The cluster was discovered by John Herschel on August 29, 1829

This is another object I left no notes about why it was on the to-do list. It went on before Kepler was running so don't think that was it. Not a great target for my system. Sometimes I wonder if it wasn't a typo but don't know what was meant if it was. Anyway since I had the data I processed it.
