An extremely scary upgrade

I have just half-completed a very scary summer project!  The Hyperstar III lens assembly is a fantastic technological achievement which turns an ultra-slow f#10 Schmidt-Cassegrain into an ultra-fast f#2 Schmidt-Camera.  There is a slight problem though with all that glass … Continue reading
