Description: Pretty large planetary nebula which has a low surface brightness. That makes it difficult because high magnification is needed for faint and small details but at the same time nebula fades considerably. The UHC filter increases the contrast conveniently. There is a weak broken ring structure visible with averted vision. The ring is clearly brighter on the southwest and on the northeast. Darker area is also detachable on the NNE side of the 13.5 mag central star.
