A Panasonic Lumix DMCFZ72, 60x optical zoom bridge camera fitted with an ICE ND100000 solar filter and mounted on a static tripod was used to capture 69 images of the Sun at ISO 100 and 1/1600s in a brief gap in the clouds. The images were precisely cropped/registered in Nicola Mackin's AstroCrop before being sum stacked in Siril, wavelet processed in waveSharp and post processed in the Gimp.
