The Sun has been very featurless for a while now but this just beginning to appear round the limb.

Poor seeing but testing out the new ZWO ASI 290MC. Getting a frame rate of almost 100 fps. Heavy processing required to get anything out of the turbulence. No matter how fast the frame rate, or how sensitive the camera, if the seeing is bad you still won’t get much.
