With a 20" at 73, 195 & 318x: "This shows as a faint glow under 73x. Under 195x, it is a bit brighter but little resolution. 318x = some stars around the edges (these are foreground stars). The rest is a round tight glow. When classifying, don't let the foreground stars confuse you; it really is a IV!"
Three years later with a 22" at 48x, I was able to see this GC along with two open clusters: M 7 and Cr 355 (Trumpler 30) in the same field.
