Two weeks ago I tried to observe planetary nebula candidate Patchick 27 after hearing about a positive observation by Reiner, who also contributes observation reports to deepskyforum.
Patchick 27 is located near Pickering's Triangular Wisp, as can be seen on this photo (circular smudge in the upper part of the photo): http://cosmicneighbors.net/pa27.htm
It is located at RA = 20h48m58.2s DE = +32°18'16" (J2000.0).
I was using my 12" Dobsonian with my O-III filter and various magnifications (49x, 84x, 168x) under NELM 6.7 mag skies, but I could not see Patchick 27.
Probably 12" is not enough aperture, but anyway I decided to give it a go.
Did anyone else observe it successfully? I'm interested in the minimum aperture required to do so.
Please find attached a sketch of what I saw. This includes filament F of the Veil Nebula (as it is called in this report by Steve Gottlieb: http://www.astronomy-mall.com/Advent...%20Nebula.html
and another filament at 20h49m37“ +32°16‘. (Does that one have a name?)
I marked filament F with an "F", the "no-name (?)" filament with an "X" and the position of Patchick 27 with an arrow.
