Good luck with the search just bear in mind a few things, as Brent said it appears visually as a slightly darker patch in a dark area of sky, it is very small really only a notch in the background.
Personally, and I would be the last to discourage anyone from trying for a target, there are lots of better, more interesting and exciting targets around.
I have observed and made notes on now over 1000 objects and have never needed a H beta filter.
