The unfortunate reality is wider image circles require must more expensive optics, heavier cameras, stiffer tubes/focusers, much better mounts to handle the right angle moments, etc
I still think a Newt rig set up to exploit the "sweet spot" for a given scope is hard to beat, and QHY has made CCDs available to people that otherwise might not have been able to "have a go".
Always something to lust for, isn't there
