Excerpt: I have no undisclosed interest in Coronado or its products and I purchased this item via normal channels. All included pictures are my property. My first view of the sun through a hydrogen alpha filter probably occurred during a science education conference held annually in New York.
Conclusion: The Coronado PST is an impressive instrument priced within reach of the amateur astronomer. It can provide detailed whole disc views of the sun, revealing prominences, flares, sunspots, plague, filaments and “orange peel” surface detail.
