O-III or Broadband for Nebulas?

Since I can't afford both - - what type of filter
would you recommend for observing Nebulas?
I have a Schmidt-Cass scope.
Thanks

Mike,

Of the two you mention, I would definitely go with the O-III over the Broadband, BUT ...

I think an Orion UltraBlock or Lumicon UHC would be a better overall choice. Currently, I own only one, and its the UHC (same as UltraBlock).

I found this article --> http://www.cloudynights.com/accessories/filters.htm
helpful.

I don't mean to ruin the ending, but it says if you can afford only one, get the UltraBlock or UHC. If you can afford two, add in an O-III. If you can afford three, get the H-Beta. I don't think the "broadband" (aka Light Pollution) filters are recommended very highly.
