[Norman]

Hello folks,
has anybody of you seen this feature in any kind of observing technique or at least heard about?

Tried it several times but I only could pick up the very first beginnings from the main body. It looks like a hood and spans around 1'-1.5'. Along the NW side it reaches to a 16mag star. I never saw the single thin filaments.

Did you try it with H-alpha equipped NV during the HTT meeting?

[Norman]

Yes i/we did - with 33". In a position angle of around 100-110 degrees a little short cone reached out of the middle of M82 (down left quadrant in your sketch).
I´ve been the only one of 4 observers to detect that, so no confirmation.
All in all it sounds very similar to your observation without that electronic aid. No fine filaments have been visible.
