AR12653 in Ha - 22nd April

Albeit renumbered, this is the second time round for this active region on our star, it appears to be somewhat decayed now with a fairly inactive single spot and trailing region of plage with associated filament material.  This image was taken with the 100mm Tal100R refractor with a double stacked Daystar Quark, Daystar interrerence eliminator and a PGR Chameleon 3 camera using 2x2 binning to help to freeze the poor seeing that was prevalent in the unstable northerly airmass that we currently have.
