Hi,
you want to go from T2 male to 1.25"? then this might be something:

or if you want to do it better you can get this one:

what about the visual back?

Hi Mark: sorry for going back on this. Do you have direct experience with this adapter connecting to an eyepiece or camera from a TZ-4 or similar Baader telecentric ? Do you have any image you can share ? Only because if I order one I do not want to make a mistake...

Thank you,

Franco

Not directly to the Baader telecentric. Is there an optimal distance the camera needs to be from the rear of the telelcentric?

In TZ4 it is 230 mm. I also bought it recently, and waiting it to arrive 😊

Baader sent me the document and there is this image. They say for the TZ-4 220mm distance, but it still unclear to me, based on this image, what is the order and length of the extensions before and after the telecentric, position of the TZ-4 and finally position of the camera at the end.

Appreciate your comments.

Thank you,

Franco

Hi Franco, im not a TZ user but the image i would interprete as this:

The tz4 can go directly to the scope via the T2 interface, 2" to T2 adapter needed.
From the end of the tz4 to the camerachip the distance has to be 220mm (etalon etc. included).

youre welcome, and the additional T2 enlongation in front i guess is optional, so that the focuser doesnt need to be that much extended to reach focus.
But lets best hear comments of tz4 users to be sure.

Yes Franco, the whole thing confuses me, it took me a very long time to understand it but it is exactly what Dennis said :)
