This is not a real cluster. Just an chance alignment of stars.

This is only nine minutes of total exposure time. What makes this worse was it was through high clouds. Not the image I wanted. I'm posting it anyway. Hopefully I will get some real data soon and be able to replace this image. Processing wise it's a little hard to do much with a shoot through clouds.

In the mean time it is an interesting cluster.
