Sun: Baader Filter Density 5.0


Only had one quite usable frame of the Sun today before being clouded out. A new group AR11313 (unofficial) is emerging in the SE limb. Seeing was bad in my area and I had to push to ISO400 1/125 to stop the turbulence. But of course, it wasn't enough. I need a Density 3.8 filter.
