I had checked the specs on Celestron's site and it is listed as a star diagonal - thus the confusion. I had suspected what you have just confirmed so thanks for that.
Due to an error by a supplier, I have ended up with 2 x 9mm WA eyepieces. The vendor does not want one returned due to the expense of tracked postage, so one for the grandson's scope.
Last night I put one in the prism diagonal and one in the dielectric mirror diagonal for comparison. The difference in sharpness and clarity is quite obvious. So all good, thanks again.
