Plage Closeup in CaK - 23rd February

There was a patch of plage exiting the solar disk today from a relic active region from previous rotations.  Seeing was not great but I imaged at 2.5 focal length at 80mm aperture using the PGR Grasshopper 3 ICX814 using 2x2 binning to get a better sampling rate.  As with the full disk a smaller aperture would have likely yielded better results but on the whole i'm happy with this.
