Steve, Hajü and Alvin,

thanks for your response.

@Steve
Summer 2001 - I guess you catch the minimum off FG Sge at around 16mag. To tough for the 17.5".

@Hajü
Stay in touch with that object. Very interesting PN besides the many brighter NGC/IC and more famous fainter Abells.

@Alvin
Very nice to hear a comment of you, good news that you are still in on it, even with smaller aperture. Your observations sounds that you catch the brighter "companion". But it is of course difficult to place that faint glow exactly between the stars.
