over this week a very large single spot has been traversing the solar disk
will still be visible for another 3-4 days
This was taken today .. 13 Apr 2016
f/l 800mm, 500th sec, ISO 200, f7.1 (plus whatever the solar filter added lots and lots )
The filter ( commercial one that I use) cuts out around 99.99% of the light from the sun
cheers
Dave
