This image was taken through a TSA102 (the baby version of the TOA) which is probably also considered a visual scope by Takahashi and possibly a few people out there.
In short the answer to your question is no, all the TOA's are good for imaging. Just one scope is a Petzval which has a field flattener incorporated into the scope and TOA's require flatteners or reducers to obtain a flat field for imaging. They can be used for visual work and imaging.
