Image 4: I observed and sketched Barnard 86 and NGC 6520 while using a 4-inch f/9.8 refractor on a German equatorial mount with an 8mm Plossi eyepiece for a magnification of 125x. I later scanned and inverted the sketch with Photoshop to better represent the eyepiece view. The image is orientated so that north is to the top, west is to the right.
