Paul,

It would help if we knew what your work flow was.

Are you DDP stretching or just doing a standard histogram stretch ?
Is your Ha added after the final LRGB blend or in the middle.
Are you double luminance layering

What is the opacity of your Ha Luminous channel ?

I note that the Blue channel is clipped at the white point of your stars, green is also clipping.
Thats less than ideal

Ha stars are almost always different sizes to normal RGB stars so that has to be dealt with too

Cheers

Rally
