Description:
At 44x I could see a lot of detail. I could see many patterns and lighter and darker areas in the cluster. Some stars form straight of curved lines and every which way. At 44x the cluster looked tightly packed together and could only make out some of the brighter individual stars. With my 2x Barrlow I could see much more individual fainter stars. At 118x I could also pick out more bright stars as before and could see more faint stars also making patterns. More of the faint stars appeared sharper also. At 178x I could pick out more faint individual stars near the center of the cluster.
