I have a dslr and a decent little setup but my camera isn't modified.

If I put a Ha filter on it it will collect very little data but still get some. Is it worth it?

Should I just shoot without filters the time I would spend shooting with a filter on?

I don't think it would be worth it.  The IR filter will block about half (or more) of the light that the Ha filter lets in.   You will get some signal, but you are going to need some lo-o-ong exposures.

...and with those long exposures from a (old) dslr comes noise. 

Yeah so basically it's not worth it.

 

Thanks

Your camera won't collect any more Ha than without the filer. The filter just blocks the additional sky glow/LP. The contrast might be greater, but the signal will still be just as weak/noisy. You need to get the signal up in the first place.
