The Sun has much of the same attraction for the webcam imager as the Moon: it's bright and easy to find and focus. Naturally, a filter will be required for imaging the Sun just as for visual observing, but, otherwise, the main problems for solar imagers are seeing and detail. With the Sun heating the scope and landscape and atmosphere, steady air can be a problem. Seeing always settles downs at least briefly, though, and capturing these brief instances of good seeing is what webcams excel at. Detail is the other problem. At the time of the writing of this book the Sun is quiescent, showing little more than a blank disk in white light. As the new solar cycle gets underway, that will change.
