The other scope I was considering was the Redcat, but it was not yet available (is it now?) and to be honest I decided not to be what amounts to a guinea pig for a new line. And it would arguably not suit my camera as well sampling wise. I think the two reviews are perhaps a little kind to the ED72 though. As an AP scope it needs the flattener, no two ways about it. I did a test shot without early on and the field curvature was very obvious over at least half of the FOV. The problem being the design issue where with off the shelf parts you can not achieve focus with the "right" spacing between the flattener and sensor.
I am hoping for the Skywatcher part to turn out to be right in terms of fitting the flattener on threaded connections but I think it is going to have the same focus problems. If it is more than about 6mm thick it will be an issue. By the time I sort it out on my own terms I will still not quite be in Redcat territory price wise. Even with a custom adapter I am going to land under the $1000 mark.
Perhaps just over that if I buy a T2 rotator that I have tracked down, there is a Baader one that should be solid enough to resist tilt issues that I can put between my OAG and imaging cam. I spent some time fiddling with the prism and I can't see the shadow in any camera orientation so that would allow easy rotation for framing without even having to recalibrate PHD.
