I saw this on Astromart.
It is the smaller focuser version of Mike's scope it would appear:

If you wanted to use it with an STL11 or bigger you'd need to swap over the focuser to the 4 inch greasless one and get the field flattener.
That should be readily available. It may need an adapter for the new focuser to fit??
