Who Spilled Ink on my Sun?

Typically, I can get better shots of the sun using just my phone's camera pointed through the eyepiece, (with solar filter in place so my eyes don't burn out or my mirrors melt or something else as spectacularly tragic) but I could never tell if I captured the granulation of the Photosphere or if it was just electronic noise.

This is processed in Registax using the Celestron Neximage 5, which is a ginormous improvement over whatever the name of my previous imager is. I used fewer frames here than I would have otherwise liked and I couldn't tell if I was in focus or not (bahtinov masks don't work on the sun!) So it's less than ideal... but you can clearly see what I'm going to call convection cells. It was also imaged in white light and desaturated so it's not in a pleasing artificial yellow color you might see elsewhere.

As I understand it, no one really knows how to use Registax any better than I do and that makes me feel better.

Sunspots taken with my phone camera (which is why there appears to be darker, shadowy areas on the disk) through a newtonian reflector at, I believe, x75 magnification, and a baadar solar filter in place. At the time I was sure I could see convection cells in the photosphere, but here any granulation is probably electronic noise.
