At 17 emission-line objects, mainly PN, the seeing disc has been compared with that of some surrounding stars (CCD frames taken through B, V, R, [OIII] 5007 Angstroms and H alpha filters). Nebulosities were found at: CPD-53.8315 degrees (0.5" in x-direction, 0.4" in y-direction), H^2-2 (0.3", 1.4") and CPD-56.8032 degrees (1.3", 1.3"). Further small nebulosities are possible at MWC 560, MWC 574, LS IV-12.111 degrees and HR Del, but they should be considered as rather uncertain. Besides, the known outer nebula at CPD-53.8315 degrees (2 condensations, 11.6" separation, PA = 146 degrees) was observed, and the author discovered a circular halo of 50" around Hb 6 - both outer nebulosities visible in the light of H alpha. Based on observations collected at the European Southern Observatory at La Silla, Chile.
