Does anyone know where the offset spot ought to lie upon the face of the secondary of the Epsilon 180 ED 2.8 ?
I might as well come clean and tell you all that, as I had the opportunity to take out the diagonal when the primary cell was taken out, ( see: "Collimation Woes" here ) it was an opportunity to give it a dust down and a clean. ( blower>sable brush>distilled water>isopropyl alchohol ) I imagine the collimating spot got lost when the diagonals' face was spray drenched with the alchohol to evaporate dry.
Truly spotless now. :S I might suppose now that it was probably only a felt tip spot to begin with.
Because of all the variables such as field width and f.l., as well as the ED corrector element I'm a little flummoxed about working it out for myself.
Still can't post on the the Tak.Uncensored site.
Cheers,
Bruce
