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:
ISO 50 100 200 400 800 1600 3200
Shutter speed, sec. 1 1/2 1/4 1/8 1/15 1/30 1/60
NOTES.
Use an ISO 400 film or higher. Usage of a tripod is strongly
recommended to achieve higher quality photos.
