Scientific paper

By comparing red and infrared POSS prints of the field 18h48m+0° we have identified four hitherto unknown emission nebulae. Three of these turn out to be compact planetary nebulae, two of which are probably type I PNe. None of these three nebulae has an IRAS counterpart, which indicates that they have small, if any, infrared excesses.
The emission-line ratios in the spectrum of the remaining nebula, HHG 33.3+0.2, indicate that the gas is excited by shock. This, combined with its structure, indicates that HHG 33.3+0.2 is a Herbig-Haro object. This nebula is located near the well-studied reflection nebula GGD 30 and is probably related to a molecular cloud at 1.7 kpc.
