Description:
A rarely observed protoplanetary nebula I’ve first read about in Cloudy Night’s Sketching forum. It’s as small as expected, but much fainter. Elongated to the N-S, with a clearly visible dark band divinding the nebula to to halves, when the seeing gets better for a few moments. Reminds me of a faint little nearly edge-on galaxy. I haven’t checked photos of this object before my observation, so I’m quite surprised now that I’ve seen the dark band, because even on a sketch made with 600mm scope it does not show up. But I know that my eye did not lie. A highly recommended gem.
Cheerio, Ferenc
