I do like observing DSO's such as galaxies and Nebulae.

My scope is a SW Heritage 130P.

Is it worthwhile investing in a nebulae filter for this scope?

My observing location is quite good but by no means a dark sky location.

I'm thinking of a filter in the region of £40-50

Thanks in advance.

I used an OIII filter on my 12" dob.

The filter did seem to cut a lot of light out, a 130 scope might not be large enough for one of these, I think they (well the one I have) is recommended on 8" & over scopes.

The Baader UHC-S filters are especially good in smaller aperture scopes. Personally I think an OIII would be to "harsh" for a 130mm scope and you would be dissapointed in the views.

The clue is in the title of your thread though - they are only effective on nebulae - for galaxies look for darker skies !.

Yes i was WRONG to include galaxies.

I really did only mean nebulae.
