Thanks for contributing Allan.
To clarify, I don't own a TOA (yet).
Referring to my opening post, I am looking for domestic collimation options. The luxury of sending a TOA back to Takahashi in Japan has long been an option for southern users - but expensive.
Yes, collimation can be complicated. I don't claim to be a collimation guru, but after using laser collimators, Catseye gear on newts, the Takahashi collimation scope on Mewlons and general collimation software - I can appreciate the complexities that must accompany collimation of an air spaced triplet, like the TOA.
Please do speak to your expert friend, as it's that sort of domestic option that I am attempting to investigating here...
