Relic Active Regions Closeup - 9th February

The sun may at times appear to be blank and featureless but there is often the subtle details, here is a old relic active region from a few rotations ago revealing itself as nothing more than turbulent plage.  Taken with the SM90 and 2.5x barlow with the PGR Blackfly IMX249 camera.
