If the final image coordinates are required in the form of punched paper tape, the card punch A 
of Figure 5 will only handle the „control cards“. In this case, the recording proper is taken over by 
a tape punch (operating on the 5, 6 or 8-channel system), which is housed in the table of the auto 
matic typewriter. 
Summary 
The BMK Ballistic Camera by Zeiss can now be supplied with focal lengths up to 600 mm (24"). 
The author gives a few data on one of the available lens types of 460 mm (18") focal length and 
mentions briefly the installation in azimuthal and equatorial mounts. A short description is given of 
the operation of a punch-card controlled mechanism for the rough setting of selected stars, which is 
intended for the plotting of star plates in comparators.
