A really nice looking cluster Raymo
You appear to have some coma on the left but not on the right. Is the right side cropped or did you have some tilt going on ?
This image is a great example of something I've been observing. Clusters of 3 stars in relatively straight lines. There's heaps of them particularly in this image to the right and up of the cluster but they're everywhere. Does anyone know what this phenomenon is ?
