Comments I took a image of the Sun today hoping there may have been some sun spots on the Sun today. As you can see there is a small one on the centre left hand side, still not much activity as far as sun spots is concerned. I was surprised by the exposure times. This image was taken at 1/8000 of a second and it was still over exposed. This has changed since removing the IR filter from the camera , exposure time used to be about 1/3200 of a second before removing the IR filter.
