Cool shot, Andrew! It's really neat to see the noise at the edges and see how it gets cleaned up as more images overlap toward the center.

Sorry, I've been a little distracted lately, but I'll get to the changes that we mentioned in the next day or so. The issues you mentioned with the short exposures could be related to timing of the download code. Unless the camera has some external memory, the little microcontroller in the camera can't buffer a full frame so it's possible that it needs the host to be ready (ie, have requested a bulk transfer) before the exposure is done. It's possible that the driver isn't meeting that timing for super short exposures. I think this would be difficult to fix without changing things too much. It would be a lot simpler to limit short exposures to a value that we know works. Any thoughts?

Thanks,
Ben
