Nice PN, unfortunately very low in the sky for Middle Europe.

I had one old sketch with 16", made from an High Alpine place (~47°N). The two main shells were visible, with different sizes and somewhat slightly structure in the shells.

Last new moon I had the chance to get very good seeing conditions at an also High Alpine (5100ft) place which were very rare here in the winter. I wanted to revisit the PN since three years and finally got the chance. I was astonished about the details which were visible. With high magnification the double knot structure in the S was the most prominent feature, following from a nearly stellar peak in the NW and a longer section at the N edge.
