AR12414 CaK Closeup 12th September

I don't have the Airylabs 'Solar Scintillation Monitor' acting as a trigger for the acquisition software yet, but it is still possible to use the data from it to see what time the best seeing was and then process the image files from this time.  The image above is a result of this process, and while not necessarily apparent when viewed at this small scale, there is a lot of fine detail visible; in particular the penumbral fibrils are starting to be resolved, which considering the image was taken using 60mm aperture is quite good.  The image was taken at 1900mm focal length with the homebrew CaK filter and the PGR Blackfly GigE IMX249 camera.
