AR2367 and AR2371 dominating the solar disk

I have been experimenting with how many images can be successfully captured and stacked with an equivalent focal length of 1200 mm with the camera on a static tripod. The more images that can be incorporated into the image stack, the greater the signal to noise ratio and more detail can be extracted.
A static tripod mounted Panasonic Lumix DMC-FZ72 bridge camera at 60x optical zoom, fitted with a Baader solar filter, was used to image the Sun. The camera was set to burst mode, ISO-100 and 1/1000s exposure at f/5.9. Images were captured in bursts of three. 102 images, precisely cropped and registered in Nicola Mackin's AstroCrop software were stacked with optimum derotation and wavelet processed in Registax 5.
