It's a lovely shot, but it does highlight what I believe is an issue with these NG refractors - soft focus and noticeable CA.
No matter how I tried focusing the NG127 I had - to include a Moonlite stepper motor focuser controlled by the computer - I could never achieve snap-sharp focus with it, and the FWHM values always seemed high (whereas my Vixen refractor I can easily get sub-1.00 on good nights).
