this is my first post here at deepskyforum and probably the first post from germany I want to start with an appeal to the advanced observers.
In a few weeks we start our annual deep sky meeting here in Germany (we call it “Deep-Sky-Treffen, DST and it starts back in 1999). I want to give there a lecture regarding PN Halos.
Beside my own observations I want to show other observations. So I will be very pleased if some of the guys here could send me some observing reports of these outer PN structures. Well known examples are the Halos of M 57 and M 27. But these are not the only Halos for visual observers. For example there is well detectable glow around the “Blue Snowball” or the well known “Cat´s Eye” with it´s bright condensation IC 4677.
The structures around the “Ghost of Jupiter” NGC 3242 are Halo-Structures and maybe a target for tough guys with large Telescopes under true dark skies.
So please, if you have any observations regarding these “outer structures” please send me a note.
