Generally, we'd all like to improve the sharpness of our astro images, and frequency separation can help. But frequency separation does not, in itself, improve sharpening. Rather, it divides an image into two layers, one containing color and luminosity information, and one containing detail information. Sharpening operations can then be performed specifically on the detail layer, reducing the chance of devolution into artifacts, grittiness, and allowing for closer inspection of sharpening effects.
This is the first episode of a new five part series on improving sharpness and image quality.
