2.Remove the rubber eyepiece guard from the scope.

3.Set the eyepiece in the medium position.

4.Screw the adapter ring with the camera in an internal groove of an eyepiece.

5.Switch on the device and focus the assembled system with the help of the objectives of the device and camera. If the image cannot be focused the camera with the ring should be removed and the coupling of the eyepiece of the device should be rotated a little. Assemble the system again and check it’s focusing. At some position of the eyepiece and objective of the camera the system will be focused exactly.

6.Fasten the adapter ring with the camera to the body of the eyepiece of the device with the help of three locking screws. During further photo shooting sharpness of the system is obtained with the help of the objective of the DN 310 only;

7.Set diaphragm on the objective of the camera equal 2.8 or 4 (shooting is possible even at lower diaphragm settings, for example 2, but the obtained pictures will have worse resolution). Taking photos with a completely opened

diaphragm of the objective is justified for the shooting of quickly moving objects only.

The TTL system, which is installed at most SLR cameras, easily estimates exposure during the shooting with the device. If your camera is not equipped with the TTL system, the table can approximately estimate the shutter speed at the diaphragm number of the camera equal 2.0:
