To the honor of Halloween

Updated to 1960x1470 resolution when downloaded

This is a 2D-slice of the eight dimensional pentic parameter space using the standard setup of parameters z -> z^5 + 5/3[ab + ac + bc - (a + b + c)^2]z^3 - 5/2[abc - (ab + ac +bc)(a + b + c)]z^2 - 5abc(a + b + c)z + d, critical points z = a making the set M1, z = b making the set M2, z = c making the set M3, and z = -(a + b + c) making the set M4.

*a_real = #pixel (horizontal)
*a_imag = #pixel (vertical)
*b_real = 0.46
*b_imag = 0
*c_real = -0.46
*c_imag = 0
*d_real = 0
*d_imag = 0

If you zoom out, you will see that the outer structure also is a degree 3 Compass. Check my previous deviation CompassBorder. However here we’ve glided a little bit longer along the non plotted axis’

Ultra Fractal, formula Pentic Parameterspace3 in the sp3-module written by my dear friend Stig Pettersson, Greenseng here at DeviantART. All his modules, as well as mine can be downloaded from here.
