USING THE POLARIE
:Wide-Field Astrophotography Mode
If this mode is selected, the Polarie follows stars at the same speed as the diurnal motion of the stars. It is suitable for capturing dark stars and
faint celestial objects. It is possible to avoid star trails but the terrestrial objects are trailed in long exposure.
The table below shows allowable maximum shutter exposure times to hold pinpoint star
images subject to a polar alignment at an error of 2 degrees.
: Solar Tracking Mode Lunar Tracking Mode
Since the Sun and Moon appear to move across the sky at a different speed than the stars, Polarie includes a Solar and Lunar rate option. These
rates are useful especially during an eclipse, allowing the user to maintain constant tracking on the object for up to 4 hours."
CAUTION: Never look directly at the sun with your naked eyes or through this product or a camera mounted on the Polarie. Permanent and
irreversible eye damage may result.

Note
*1:The above focal lengths show actual focal lengths
of your camera. It is not necessary to convert
them to focal lengths in 35mm film format if APS-C,
3/4 or other format is utilized for your camera.
*2:The above exposure times are calculated on the
assumption that the pixel size of an imaging device
is 0.001mm. Allowable maximum exposure times
will change according to the specifications of your
camera and lens. It is recommended you test your
system to determine the best exposure time.
*3: The above exposure times will be extended by three
times and more if you use a 35mm film format camera.
