Abstract: 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 A and H-alpha filters). Nebulosities were found at: CPD-53 8315 (0.5" in x-direction, 0.4" in y-direction), H 2-2 (0.3", 1.4") and CPD-56 8032 (1.3", 1.3"). Further small nebulosities are possible at MWC 560, MWC 574, LSIV-12 111 and HR Del, but they should be considered as rather uncertain. Besides, the known outer nebula at CPD-53 8315 (2 condensations, 11.6" separation, PA=146) was observed, and the author discovered a circular halo of 50" around Hb 6 - both outher nebulosities visible in the light of H-alpha.

Key words: planetary nebulae: general; stars: symbiotic; stars: novae; stars: horizontal branch
