The original Lumicon H-Beta filter was marketed as the Horsehead nebula filter but it does so much more. Objects that are viewed best with UHC look different in O-III which is UHC minus H-Beta and also look different in H-Beta which is UHC minus O-III. I find a H-Beta filter presents a different view of an object I would normally use an O-III filter for provided the object is emitting in H-Beta too.
I didn't think any line filter was good for galaxies.

Oh, no.
I was merely talking about Horsehead and faint nebulae near the limit with the list of H-ß objects.
No filter will help with galaxies except gasoline--you put it in your car and drive your scope to darker skies.
I wasn't thinking about galaxies with the list of faint nebulae.
I mentioned galaxies because objects near the limit will mostly be faint nebulae and faint galaxies. Sorry for the confusion. Perhaps it should have been 2 separate answers.
