Hi Patrick
These DOBS look really nice, interestingly the electronics has a ST4 port for guiding (rare for an Alt/Az).
I think Sirius Optics in Brisbane had a 20 inch on order for display.
If you have been following the Cloudy Nights thread, you would have seen this video of the 20 inch being setup at The Texas Star Party. Howie (Glatter Fame) makes a visit.
