I have to make a panorama of a ceiling vault of a church and I will use a 200mm lens. The problem is that I can't make a perfect nodal point calibration because when I point on the zenith the sliding bar with the camera body would beat against the head structure. My question is: do you think I can avoid the calibration of the nodal point and use the "multiple visual" option in the creation of the pano? Do you think it could be possible to reach in this way a good metrical result (i.e. no deformation in one or more axis)?
Thanks for you attention

That was my first idea but I work with a Clauss HD and technicians told me it could damage the engines of the head. So the second idea (if mutiple point doesn't work properly, but I really hope it will!) could be to take two partiale panos and stitching them as one: where can I find some information about the stitching of two or more panoramas?
thank you

my head is this one:

The difference with the "perfect" calibration, I think is about 10cm along focal axis, so I don't know if multiple point could work. Another idea: I make a perfect calibration to take all the ceiling vault but the zenith area for the problem of disturbance of the head structure; then I take the zenith are without calibration using the multiple viewpoints; finally I stitch the two panos.
What do you think? Do you have samples about the stitching of two panoramas?

first of all congratulations for your image: it is great! Is it an HDR image? How did you do for focus issue: manual, af assistant ...?
In my work I will do just the panorama of the ceiling vault (not the full sphere) with my D800E with Nikon AF Micro-Nikkor 200mm f/4D ED-IF, so (for the total weight) I am not sure to rotate the Clauss!
What do you think?
best, Leo
