Peter the first two look like astigmatism , but the two on the right are text book perfect !
Collimation perfect in all images . Good news If Its from the toUcam , If the objective was astigmatic It should reveal It self at 200 x as well.
When you checked It out visually using the star test at high mag what did you see ?

Cheers
