Description:
A faint little planetary discovered by Herschel. It has a diametre of 1', even at 71x it does not look like a star, but rather like a large, fuzzy little spot. By increasing the magnification, you may notice a slight elongation in the WSW - ENE direction. By some more careful examination, a slightly brighter central region is visible to the ENE, with a faint star on its edge, which I thought to be the central star. However, as I went on with the sketching, I started to notice an even fainter star in the middle of the brighter core area, first only with averted vision, later on with direct vision too, which I believe is the real central star of this planetary.
