Comments on Pretoria eyepiece???
As you may have seen in the buy/ sell and on AM, I'm trying to find a Pretoria eyepiece. So far no success, but I was hoping someone might have had one who could comment on the " coma" correction for fast systems.
When these were designed by Klee back in the 80's they caused quite a stir but for some reason UO did not maintain production. BTW the Klee barlow, developed at the same type is still available through Helix in the US.
Anyone got any info!!!
