John continues to take fine images of the Sun using the simplest method of hand holding the camera to an eyepiece. I have tried his technique but continue to be astounded by the quality of these images! A steady hand is key to achieving this resolution of image.

The Sunspots are from right to left 741, 742 and 743.

There are 2 slight artefacts which seem to be either dirt on the lens of the camera or telescope at the edges of the photosphere.
