Hi

I am not a PS user, but another route is the principle blending exposute (apart that you don´t use 2 different stack exposure, but as you did, a single frame for the core (also you can maybe used a non streched stack and a streched stack for the rest): use mask/blur/curve as explained:

also you have a lot more data in your picture: I downloaded you jpeg and gave it a level stretch in GIMP: a lot more comes out.

Thanks for that Erguy! That looks like a neat way of getting the result I am after. As the weather isn't that great still (haven't been able to get out and obtain any more data) I may as well play around a bit more with this image. I will give it another stretch and see what I can come up with.
