just distortion from atmosphere and processing,  you will never see spicules with astrosolar film.

 

You can however mask your objective with a  Bg25 piece of glass stacked with Ug11 glass and the baader filter on the camera to achieve very wild results.    Be warned however, this can get be dangerous if you are not careful and it takes some skill to do this properly.

You can find the glass filters on ebay.
