Bloated Stars

[themongoose85]

Does anyone have a way to tighten up the faint outer halo-like area around these stars? Everything I have tried so far reduces the star size but leaves this outer faint area intact.

These look ok to me. The brightness profile (PSF) of a typical star should be a Gaussian distribution(bell-shaped curve) not something ending in a sharp boundary.

I agree but I am having difficulty due to the significant difference in the halo 'size' between the R, G and B subs.  Integration usually results in prominent coloured fringes that I (yet) can't seem to control.

There are procedures for this.  Would search on bloating.  Or try this secret sauce:

Thanks Jerry,  I tried that some time ago with little effect for me but have it in my 'diary' to persist when all my subs are in.
