Hi everyone,
to my understanding you will never succeed aligning telecentric images, whether stacked or not. A telecentric lens has infinite focus, so Photoscan will not be able to locate the cameras. In principle, it should be possible to include infinite focus cameras into Photoscan, if homogeneous coordinates are used internally (which is probably the case), but it seems that Photoscan at the moment is not able to handle such cases.
You can however use a regular (non telecentric) camera for focus stacking, if you resize the images correctly. Commercial stacking programs (e. g. Helicon) do this.
