The Sun with Sunspots

The Sun with Sunspots

This picture was taken during the summer of 2004 during the day using a solar filter and projected on to the film plane of the camera. The delay function of the camera was used. The f-ratio of the telescope controlled the time exposure. The telescope used was my home built 8" with an f-ratio of 9.75 and was unguided.
