KAI11002 gives .93 arc secs per pixel on a 10 inch F8 scope. Half that with the 20 inch F8 (.46).

Case in point, a 10" has a resolution around the 0.5" where as the 20 is closer to 0.25" but if they both have the same focal length the 20" slaughters the 10" because it captures images 4x faster and is able to go deeper (capture fainter objects). Putting a KAF-11002 with its 9 micron pixels will give a resolution of ~0.91 arcsec/pixel which would be pretty much perfect for normal every day imaging.
