So it cannot be the reducer. That is ruled out.

Are you imaging with the mirror up prior to release?
Eliminating the shiny parts is a good idea anyway.
Adapters was raised and that is a good idea too. Something in the later part of the imaging train is causing this issue.
Don't worry about the baffle now Doug. Now that I have thought more on this it seems very unlikely this is a problem. I will ring and have a chat. See if we can nut this out.

Thanks Paul - appreciate it.
No mirror lock up used - will check it out.
Another thing I realised while painting the shiny parts(!) was that when I removed the Losmandy D plate in order to save weight, I returned the allen bolts into the OTA. It looks like they protrude into the OTA but not below the first scope baffle blade - I removed them too and covered the holes in the tube.
