I believe the camera ought to do two things-

Arm the scope's single sweep mode automatically when you open the 
shutter (or vice versa- open the shutter when you arm the single 
sweep) so the film captures exactly one sweep.

Turn the graticule light off while the shutter is open, apart from a 
short blink just long enough to write the image on the film.

On my R7603 there are three little contacts to the right of the 
screen and I guess this is what they are for- ground plus each of 
these two functions.


If your digital camera had a cable release input (mine does) and the 
C53 had an electromechanical shutter, it should be as easy as 
connecting a relay coil to the shutter coil and having the relay 
contacts trigger the camera's cable release button. The camera would 
be set to "B" so it exposed for as long as the C53 told it to. 
(presumably the C53 closes its shutter after the single sweep fires.)
