Thats a great article by David Kingley, Suzy - love the section on all the nebulas and which filter is best.
UHC is the overall filter winner.
And ....
VEIL NEBULA NGC 6960-95 (SNR in Cygnus)
(10 inch f/5.6, 52x).
DEEP-SKY: (3) Nebula is easier to see than without a filter, with both sides of the loop being visible, including the section through 52 Cygni.
UHC: (4) Large increase in detail and contrast! Nebula really stands out with some filamentary detail. Hints of other strands in the interior of the loop.
OIII: (5) ENORMOUS INCREASE IN CONTRAST AND DETAIL with wonderful fine filaments and strands visible even between the two main arcs, making the entire complex closely resemble its photograph. OIII is the filter of choice here.
H-BETA: (1) Very dim, but still visible (forget it!).
RECOMMENDATIONS FOR VEIL: OIII/UHC (OIII is somewhat better but H-BETA is
NOT recommended).
