AR12651 in Ha - 23rd April

This active region and its associated plage and filaments is framed nicely in its entirety with the Tal100R refractor, Daystar Double stacked Quark, Daystar interference eliminator and the PGR Chameleon 3 with 2x2 binning to freeze the seeing and shorten the exposure time and increase the frame rate.  The 0.7x Baader Solar Telecompressor also helps matters by bringing the focal length to near 3000mm.  This setup has a real synergy, and in summer months allows effective imaging at this scale on most days.
