The DSLR capture assumes you've set the camera exposure time to 10 seconds.


# Notes
The call to `jpg2fits -d 0.264 -T 10.06` has arguments with a delay between the gphoto2 call and the shutter actually opening, as well as the actual exposure time.
You can measure this by recording audio of the shutter opening and closing, super posed on computer generated beeps at 1 second boundaries
