That may be the problem. Since the Star D has no IPD adjustment
it's hard to see what effect viewing ON vs. OFF axis has.
If you were to take the lenses of the Star D or any simple
element lens and vary the IPD you'll notice chromatic abberations
quite readily. 

But then again you're talking about designing a multi-element 
lens so this won't be near as much a problem.
