Hi Greg,
That would be very interesting! I have the ONAG. There is somewhat less light to guide on in the IR. Your test would be very interesting if you can do a comparison by somehow using the exact same guide exposure and comparing sub frames for FWHM. I suppose, however, if you had to use even longer guide exposures and got better FWHM that would also constitute proof of some sort. Looking forward to seeing your results!
Peter
