This step is a good example of how useful it can be to create a new layer in a temporary file and then drag a copy of the finished layer into the development file when it is completed. This approach can be particularly useful when one needs to experiment with merge modes or color transparency masks of the new layer during its development without allowing confusing variations of underlying layers to show through.

Creating a new fractal in a new file and then copying it to the developing file is also a good way to try new formulas with the defaults, including color gradients and fractal coloring, selected by the formula authors. It facilitates variety.

In actual practice, I would at this point just try some promising-looking formulas to see if one of them might be used to create a radiant superstar, almost a sun, with bright radiation lines.

As it worked out, however, I was able to use one of the first few formulas I tried to create the star:
 

 
This will cause the Select Fractal Formula dialog box to appear.
 

 
The image produced by this formula with auxiliary formulas and variables as envisioned by the formula author should open in a second Fractal Window (which should now be the active Fractal Window) and should look like this:
