Ha Full Disk - 23rd March

 Weather conditions were far from perfect with some haze with the sun low in the sky, but with the lack of decent weather so far this year I was not giving up on the chance to observe our star.  The new sunspot isn't particularly outstanding in Ha, but is nice to have some activity to see.  There seem to be lots of delicate filaments and prominences at the moment on the disk.  This shot was taken with the PST double stacked with a Lunt 50 etalon, at 400mm focal length with the PGR Chameleon 3 camera.  1000 frames were taken and 100 stacked in the new beta version of Autostakkert, which, I have to say works very well and seems to have some interesting new features.
