Your supplied picture looks practically identical to what I saw with a Takahashi FS-60CB during daytime viewing. It is the lack of knife-edge baffles within the drawtube causing stray light to bounce off the drawtube interior and throwing a veil of glare across the field of view. Sometimes subtle, other times very much contrast-killing. When I looked obliquely through the eyepiece, the veil would shift out of sight, more easily achieved with larger exit pupils.
If the FOA-60 is similarly without at least one knife-edge baffle in the focuser drawtube, then it’s possible that’s what going on. At any rate, Takahashi’s standard blackened anti-reflection threading within the drawtube does a very satisfactory job of stray light control during astronomical observations.
