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 didnt 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.
