Feel the need to spend a few quid.

My main scope is a SW Heritage 130P.

Will any of these filters improve things with regards to observing Nebs in the long dark days of winter:

UHC & OIII Visual filters

If so which will be the best to buy? My scope takes 1.25" filters.

Thanks in advance.

Hmmm..... a nebula filter mabye? I think OIII fits the bill but there are different types to check out

I think you might find a Baader OIII a little too "severe" for your scope - they are a particularly narrow band pass OIII and work better with medium to larger aperture scopes IMHO. Before I discovered my current Astronomik OIII, I had an Orion Ultrablock UHC filter which I used with my 4" refractor - that worked pretty well on a wide variety of nebulae. I'vr also tried the less expnsive TS UHC filter (TS = Telescope Services, Germany) and that seemed quite effective for it's cost.

I have the Skywatcher UHC and I am not particularly enamored with it. You could buy it and give it a go but its 2".

I'm a Baader filter fan myself, I have the BAADER NEODYMIUM & IR Cut filter, the Solar Continuum and the O-III and they are superb quality. Been very impressed with them.

With these filters you need a nice, large exit pupil to push some light through them. That's certainly possible with the Heritage 130p but magnification is low with such a setup and planetary nebula tend to look too small. That's why larger scopes are recommended for the use of filters.

Being the owner of such a filter, I don't think it would work out well with your setup.
