White Light Full Disk 6th March 2011

I'm continually amazed at the performance of this little 70mm f6 refractor and the Lunt Solar wedge used in conjunction with the Baader solar continuum filter. This image was taken with the PL130M, and in order to image needed 2 neutral density filters in the optical train to bring the exposure to an acceptable level. Detail is very promising. I'm really looking forward to being able to use the wedge with my 5" frac as the year goes on, which will give increased resolution at a longer focal length.
