The space photosurvey is carried out 
synchronously by all four channels of CA-M and star 
camera CA-3P. 
Four chanels of CA-M can be mounted by 
objectives from six possible versions designed by one 
scheme. 
The objective consists of 9 lenses, built-in 
light filter situated near to aperture diaphragm and 
levelling glass. The glass and the light filter are 
the parts of the optical system.
