+
+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
