  "abstract": "The jets seen in NGC 6543 motivated us to search for similar features in other PNe. Our HST snapshot program looked for jets using the [N II] and H-alpha narrow-band filters. Although spectacular jets are found in proto-PNe, true jets seem rare among mature PNe. In the later group, IC 4593 is the best case in our sample. We distinguish between jets and a number of interesting ``jet-like'' features, e.g., ``cometary'' structures with a dense globule at the end facing the central star.",
