Cheers, the softness might be down to either the light whispy cloud that was around or Registax as I didn't do my normal convoluted stacking process.
Still I'm happy to be getting the Sun quite regularly now.
Well I guess it depends on the definition of normal but it is common enough.
I suppose it's more normal to use a uv/ir cut or solar continuum but from what I have seen the OIII stands up to them and depending on the set up even can out perform. Another one that appears to be very good is a 7nm Ha filter.
I'll see if I can find a link when I'm back on the PC and post it.
I basically chose the OIII because it seems better than the uv/ir and as far as I know there isn't a eos clip filter for a continuum, plus it's possible I may be able to use the OIII for other things.
I think though that it may vary from set up to set up, some people say they have better luck with differing filters but I can't say I have any others to try for comparison. A cls maybe?
