Found two itself interesting observation with different results concerning the red tails.
27", 586x, without filter, NELM 6m5+, Seeing II-III
faint, small and elongated ring; north side of the ring somewhat brighter; to the southeast a faint and broad extension becomes visible; [OIII] and Hß don't bring any positive reaction; thin arms are not visible
20", 1000x, without filter, NELM 7m0+, Seeing I
under much better conditions but smaller aperture, two arms becomes visible; one wide arm to the southeast and a thinner arm to the northwest; the PN itself is presented as a very small but open oval body
