Can i ask why the full frame sensor is so important?
The bigger the sensor the more issue you will get with curvature and tilt and all other kind of nasties.
Field of view on an image is a combination of a couple things, sensor size and focal length.....if it's field size you're after then could you not play with the focal length and a smaller sensor?
I don't think anyone will argue that a cooled astro camera is far superior to any dslr regardless of what mods it has had done to it......with the disclaimer of 'unless you want a highly mobile and simple setup'
