Sun's Binocular Projection Corrected With "Granny Glasses"

One can use "granny glasses" to corrected the projected image of the Sun created with binoculars. I attached +1.25 D reading glasses to one side of the binoculars and focused the image onto a sheet of white paper at the ground level.
The image is comparable with that of the +1.0 D lens combination.
One can just make out the sunspots.
