Haha!
Have you found with your ED127 that the orange stars focus better than the blue ones? As in, when a Bahtinov Mask reports that an orange star is in best focus, if you were to slew to a 3rd or 4th magnitude regular star, they have an ugly violet halo. I found dialling the focuser back just a smidgen would remove the halo but still present sharp stars. They weren't as sharp as at perfect focus, but, still excellent.
