Still imaging around the weather. Got two nights in through varying amounts of high clouds .... Still not enough time to show the faint nebulosity in this region, as I had to 'tone down' the glow around the cluster and the brighter stars caused by the persistent high clouds. See the 8" version.

According to "Star Clusters", by Brent Archinal and Steven Hynes, the size of this open cluster is 5.0 arc minutes.
