A few weeks ago I observed the Melotte 111 in Coma Berenice. This huge star cluster with a diameter of at least 5 degrees is actually too big for most of my instruments. I used the skywindow and my 8x42 binoculars with an 8 degree field of view for the sketch. It is a truly great object for binoculars.

South is up, East is to the left.
