Hi Leo and Mark,
Once the completed adaptor and baffle tube extension both arrive, I'll be sure to document all the bits and steps involved in reassembling and testing/collimating the OTA. This is where the OCAL will come in handy. (See my original post in this thread)
Mark, I'll check my baffle tube dimensions and post here so you can compare. I also seem to recall there are some internet posts describing the new and old GSO tube designs.
Edit: The adaptor plate sits just proud of the existing rear 90mm thread and is attached to the black OTA backplate by 9 tapped screws, with a template to be used for hole location. Drawings and photos will be available (hopefully) soon
