It has escaped

I did this last year with the 60 in ha
this time its with the FS102 and HST NB
20 each of S11 Ha S11 1800s

I cannot quite tame the halos round the stars help would be appreciated

Excellent job.

Very nice!  

re: the halos. Give us a couple of min, I'll see if my usual works......

Thaarrr ya go

How to:

1) Open in Ps

2) Open saturation window, select magenta from dropdown.

3) Now, see the left & right markers at the bottom of the saturation window? Move those closer together (it restricts the colour selection so youre not knocking out the wrong bits).

4) Using the saturation dropper icon, click on the magenta halo on one of the large stars - you will notice the colour selection slider in the saturation box move about when you do that.

5) Now you have your range of magenta selected, knock the saturation down to -65. You could go to -100% but it gets a bit noticeable.

Happy processing!

PS: If more time is spent, you could do a variation of the above on a pre-selected area (ie: just on the stars, and not applied to the whole image like I just did)

Thanks for this I need to add to my workflow.

Take it you mean a star mask to restrict without affecting other parts.

Yep, its kinda like a star mask but not so tight, as some of the halos are quite large. Noels "select brighter stars" plus a bit of expanding will pick up most of them - but there would have to be some fiddling about with the selection - or do it in two parts, small stars first - then manually select the larger ones.

I wouldnt normally do it to the finished work either, its usually applied to the RGB layer before merging it with the Lum master.

thanks for the coments

and many thanks 235 for the work through, I will give it a go on the tiff tonight
