 This is my first attempt at Ha solar photography, on a day of rather average seeing and a completely spotless sun. There were however a few dim prominences seen here, and it was a better result than I expected for a first try. The Coronado PST was used, with a Klee 3x barlow for projection. It was found that the 2x Coronado barlow would not come to focus. Also, a dozen exposures were taken rotating the tuning ring a bit in between, and the best two image for the disk detail, and the one for the prominences was selected. The combined image seen above shows the disk image superimposed on top of the much brighter prominence exposure so both may be seen in one image.
