Nothing special, standard solar film filter for my telescope. I just held it up in front of the lens and braced myself against a tree trunk. Sunspots are easy (if there are any). The dramatic shots that show solar prominences and complex features are Hydrogen-alpha narrow band filters and they cost as much as an L lens. Someday...
