White Light Full Disk - 6th May

The sun is all but blank at the moment, all bar a very small active region that contains a couple of pores, nearer the north eastern limb there is a small region of plage associated with a decaying active region.  This image is the first proper white light full disk image I have got with my 60mm f6 scope I bought earlier this year.  With it's short focal length it is easy to get the full disk in one on the frame with room to spare.  The 2" Lunt solar wedge was used along with a 656nm Ha filter.  I need to replace my solar continuum filter and try that for greater resolution.
