Wow a 17 inch AP Cassegrain. Notice the lots of holes in the main baffle. To combat tube currents. Roland is very good at engineering solutions to tube currents. I notice that in my RHA305. The outer tube is oversized to 14 inches so there is 1 inch all the way round for tube currents to fall away from the imaging circle. Also his scope will have way better baffling, another thing I find AP is superb at. Again I find my RHA 305 the best scope I have ever used for cutting through light pollution. Amazing really.
This scope would be phenomenal. Thin mirror - quick cooldown times and would match the ambient well in rapidly dropping temperatures.
Portable. I didn't see that coming. A 17 inch scope that is portable. That would make it totally unique right there.
Roland has expanded his skill set to expert mirror maker.
I imagine if this had a price it would be around US$30K at a guess.
Greg.
