AR12135 CaK Wavelength 9th August

Despite it emerging only a few days ago, and containing 2 large sunspots, AR12135 is already starting to decay and shows no signs of an up tick in activity.  There is a distinct lack of plage around it as can be seen in this image, compared to the amount of plage that there was around some of the active regions in the last week or so, a shame really!  This image was taken with the 40mm scope at 925mm focal length with the DMK31 camera and the homebrew CaK filter.
