I am confused on setting up my Baader telecentric to use with a Daystar Quantum. Per documentation the proper spacing is 250mm. Is that for the camera or the Daystar? Is that measured from the front (telescope end) or back of the TZ-3? Later in document mentions the original focus position is ~ 86 mm behind the front end of the telecentric lens assy. I interpret that as the Daystar should fit directly on the back of the tele centric (#1) and the camera should be positioned 250mm (#2)? Is this correct?

Re: Baader TZ-3 spacing asistance
Franklin. I believe you have it correct. The camera sensor should be spaced 250mm behind the rear lens element of the TZ-3. The filter directly behind the TZ-3.
The scope’s original focus should be positioned 86mm behind the front lens element of the telecentric. This is not exact for all scopes. To come to focus, I had to bring the telecentric forward relative to the original focus.
