Hi Ben,
My colleague has just responded to the support ticket that you raised around this.
iSTAR Pulsar does not have an option to capture single images, it is designed for rapid capture on either a time (frames per second) or distance (per meter) basis.
The only solution here would be to capture in line with the above, process the dataset, and then manually identify and isolate the single panoramic image that you wish to use.
Further to this, capture based on distance requires the device to be in motion, so if you are capturing while the device is stationary you'd want to use a time-based setting, perhaps 1 frame per second or similar.
