Better late than never! Here is a sketch from my observation of Abell 39 two nights ago under reasonably dark skies at Xyliatos Reservoir, Cyprus. The pn was practically invisible without a filter (I am not sure if I reall saw anything there since I knew it was there!) but it was quite easy with the Lumicon OIII in place, especially at low magnifications. Using the 31mm Nagler on my 18" Obsession (67x), Abell 39 appeared as a round, uniformly lit ghostly disk steadily visible with direct vision. Best view for me though was with the Ethos 13mm (159x). Although at this magnification the planetary became harder to see, it did seem to have a distinct intensity variation, with the southern part kind of fading out. It did remind me of a partial lunar eclipse from a vague, ghostly world!
