The Star Sketcher: Ngc 6818 planetary nebula in Sagittarius; mag: 9.3 ; size: 20" ; bright but small bluish- greenish tint, enveloped in what seems to be two shells of nebulosity, one brighter than the other. The brighter shell has at least three bright knots. The center appears to be darker, and at times I thought I was seeing the central star, but did not include it the sketch because I was not sure. This object takes magnification well so I used a 6mm Ethos at 264x magnification. I useda NPB filter and no filter for the sketch.
