Hi Kanga.

Background extraction is a way of subtracting stray light and light pollution in your back ground and removing it. PixInsight calls this Background Extraction, Photoshop has Gradient Xterminator and other software packages will have a relevant module or process.

I used to hate PixInsight with a passion. Now I will not use anything else. It is worth the effort and there are many you tube tutorials to assist.
