Hello,

So I tried to deal wuth the secondary tilt and that improved the unfocused
star pattern. At higher powers the image stays the same all around the FOV.
At low powers the image begins to change to an oval as it approaches the
edge of field.

Also, at high power, I notice that the extrafocal image shows some
miscollimation while the intrafocal image is very, very close to perfect.

Thanks for your advice.

Dan
