AR12134 Ha Closeup 4th August

Whilst this active region looks quite dramatic from this oblique angle as it sits close to the limb there are already signs it is sporting a light bridge which is indicative that it is in the process of decay.  Either way it is picturesque to look as can be seen in this image taken with the 100mm PST mod at 2000mm focal length with the DMK31.  Running at 2000mm focal length seems to be a good number with the chip size of the DMK31 as there is no real sign of the sweetspot of the system impacting on the image.
