Description:
I looked at it at both 56x and 94x, 94x better framed it, and was much more 
pleasing.  Roughly 30 stars brighter than magnitude 10, the rest are dim and I didn’t bother counting.  Many stars exist in the ‘nebulous’ background of unresolved stars, and pop in and out of sight.  Roughly shaped like a cross, but not like M38, more like an X.  The more I looked at it the more I thought that it was more spherical with some dark globules breaking it up.  Maybe not, but that was my impression.
