Earlier in the week, I have been experimenting with the PST CaK and the DMK31.  I had problems bringing it into focus.  Today tried it again.  Stephen Ramsden made the coment that I probably was 2mm out of focus, so I looked at the nose piece of the DMK31 and the mounting ring of the nose piece stuck out a little.  I need to find the proper tool to adjust this, so in absence of that, I used the DMK21.  This gave me a little more inward travel and the image came more in focus.  I believe I am still a little off, but as a first image of the PST CaK I am pretty happy.  Here AR1117 which shows pretty dramatic.
