With Geof taking delivery of his iDK 12.5 and me expecting my iDK 14.5 in the next month or so, i thought i would share the presentation that Dave Tandy from AG optical gave on the astro imaging channel. during this presentation he goes through the evolution of the iDK design, what goes into making high end optical systems, some of the decisions that were made and why.
