What is called the second closest star cluster to our sun? Looking at it with a
scope is of little use, because the grouping covers about 5° of sky. Some of its
stars look so bright in a scope, as if one can almost touch them. So here it is, my
impression of this beautiful naked eye cluster. I used the lowest power available,
but even the fov of 3° is not large enough to cover the cluster. So the sketch is a
composite image of overlapping observations. Because of the low power, the sky-glow
washes out al stars fainter than mag 10.9. I hope you like my impression.
