I'd love to know how you calibrate. Star field? Calibration target? If target, I wonder if calibration would be reliable at finite distance. Obviously, the target has to be reasonably close to be practical. I tried using Ursa Major and found that either I made some mistakes or the iphone 5 optics produce a miserably distorted field (at least for CN).
