Used the RRS pan head. For framing I used the gridlines in the viewfinder. I tethered the camera and lense combo to figure out where to mount the lens foot on the head (nodal point). By swinging the framing from one extreme to the e other. Put the figures in my now destroyed cell phone. Need to redo them )

The software did a pretty good job of sorting the frames for the most part. It is just such a pain to do the matching. Converting the raw to jpg took.... let's just say overnight. Loading the jpg into the stitcher was easy 30 minutes. This is on an i7 5500 with 12 g ram.

Creating the actual stitched image took 15 mins or so.

I suspect there are programs better suited for this size. My attempts with 22mp images and 10 frames where surprisingly fast
