Try again with the UHC, an Ultrablock (essentially the same)has work
using my 6" dob. The H-Beta is better. Last winter on an exceptional
night of transparency (NELMZ 6.5)I tried the H-Beta with my little
70mm refractor. Using an ultrawide 22mm LV at around 28X B33 blinked
in and out as a little dark kernal in the side of IC 434. I was
surprised at how well 434 showed. If I didn't know where to look I
probably wouldn't have noticed B33. Previous sightings helped a lot.

My favorite sightings are using the 25",when B33 looks like a chess
piece.
