AR12659 in Ha - 24th May

Despite being small, this active region had an interesting amount going on, the single spot was visible faintly on the photosphere, while its bipolar counterpart was seen as a small flaring region.  Dark, cooler plasma tendrils can be seen extending from the active region corresponding to the magnetic field lines.  Taken with the 0.2m Airylab HaT, double stacked Daystar Quark, Baader 0.7x solar telecompressor to bring the focal length back to about 4250mm focal length, with the PGR Chameleon 3 camera using 2x2 binning to increase the effective pixel size, their sensitivity and then reduce the exposure time with the result of freezing the seeing conditions.
