You will normally get larger FWHM in blue in most seeing conditions - the seeing varies with lambda^(-0.2) so there is a broadening at short wavelengths. My impression is that it might be a bit worse than the theory suggests - it certainly is for "lucky" planetary imaging. |
Thanks Ray, definitely going to have to read it when I get off work
