Wavelets - Request for Image Process

[Radar]

Hi P.Team

Can someone help me with this image. I am having problems manipulating teh wavelets the right way.

Here is a photo of Corona Australis. At its centre is a dark nebula.



I want to bring out that dark nebula like the nebula in the link below.

I can't figure out how to make the new version of pixinsight create small or large scale wavelets. I can create wavelets, but I have no idea what I am creating. I just experiment with all the controls and make wavelets and hope for the best. But I would rather do it properly.

If someone here can process the image in the link for me and explain to me (in very simple terms please) what they did, I would appreciate it very much.

I really want to learn how to do this.

Thanks P.Team

Regards

Ray

I also have a higher res version of that image 713k if needed.
