Hi Baz,
I am not into taking astro photo's myself yet, but I do have a photo program that I use for terestrial photo's, called Paint Shop Pro and a lot of the photoshop actions people talk about are available in this program. The only thing I am not sure of is my program is made by Jasc Software, so I am not entirely sure it is the same as the one you have shown. Anyway like i said most of the actions spoken about for adjusting photo's are available in my program.
Hope that helps.
