Have seen it in 18" fairly easily if one is used to looking for something that is not there (dark nebula). Contrast is very faint. Must use H-Beta filter or you need a lot larger scope. I know people who have seen it in 12" but I had tried several times in an 11" sct with no luck. I covered my head in a blanket and stayed in that 'tent' for 15 minutes and so on even AFTER I was fully dark adapted, still no luck. But my observing skills were lower then so maybe an experienced observer or a younger person could see it ok in a 12".

Suggest you somehow use tracking scope and with stars get right on top of it using every averted imagination and a pre-printed out DSS image on paper then use every trick you know (jiggle scope and so on). Do NOT go back and fourth from computer screen image to this object, you need every bit of adaptation you can get to see this object.

Only time I have seen the area under the chin is in a 33" and that view was of course the best I could imagine from dark skies (21.7 mag/ArcSec) and H-Beta filter. I bet you could see it in a 33" without filter.

From my location it is about in same place as you see it only upside down (to you). I am at +36 degrees on Yee-Ol-Earth.
