Stepping back a moment...

Looking at this (and various similarly evil things I did in trying to induce the stripes on my cameras) I think we should all take a moment to step back and consider one thing....

Think about the energy density of that spot!

Not so long ago, a spot much dimmer than that would have spilled excess charge all over the place giving line artifacts or neighborhood sensor bloom. Heck, we've been pointing lights at the sensor that have energy densities at the sensor that aren't too far from what I bought special solar film to prevent when photographing the Sun leading up to the eclipse. I've actually stopped doing the more freakishly bright tests for just this reason: I don't want to risk damaging the sensors....
