LEVENHUK RA FT72 ED PHOTOSCOPE
Congratulations on your purchase of a high-quality Levenhuk PhotoScope! These instructions will
help you set up, properly use, and care for this device. Please read them thoroughly before getting
started. Be sure to follow instructions in this user manual when using or storing the PhotoScope.
CAUTION! Never look directly at the Sun — even for an instant — through your telescope
or finderscope without a professionally made solar filter that completely covers the front
of the instrument, or permanent eye damage may result. To avoid damage to the internal
parts of your telescope, make sure the front end of the finderscope is covered with
aluminum foil or another non-transparent material. Children should use the telescope
under adult supervision only.
All parts of the telescope will arrive in one box. Be careful when unpacking it. We recommend
keeping the original shipping containers. In the event that the telescope needs to be shipped to
another location, having the proper shipping containers will help ensure that your telescope survives
the journey intact. Be sure to check the box carefully, as some parts are small. All screws should be
tightened securely to eliminate flexing and wobbling, but be careful not to overtighten them, as that
may strip the threads.
During assembly (and anytime, for that matter), do not touch the surfaces of the optical elements
with your fingers. The optical surfaces have delicate coatings on them that can easily be damaged if
touched. Never remove lenses or mirrors from their housing, or the product warranty will be null and
void.
Using the PhotoScope
Note! A tripod, diagonal mirror, diagonal prism, eyepiece, eyepiece adapter, eyepiece adapter
dust cap, photo adapter, T-ring and DSLR camera are not included in the kit.
As a spotting scope (fig. 1 and 2)
• Set up your tripod on an even surface and take the scope out of the aluminum case. Use the
dovetail mount to attach your PhotoScope to a tripod (there are two tripod sockets on the bottom
of the dovetail mount). Remove the objective lens cap.
• Loosen the locking screw and insert a diagonal mirror or prism. For visual observations, insert your
eyepiece into the eyepiece adapter. Tighten the locking screw. It is recommended to start your
observations with the lowest magnification.
• Look through the eyepiece and focus your view by rotating the coarse focus ring.
• Precise focus adjustments may be done with the fine focus ring. Now you can start observing.
As a camera objective lens (fig. 1 and 3)
• Loosen the locking screw and insert a photo adapter. Tighten the locking screw.
• Thread a T-ring onto the photo adapter. Attach the resulting objective lens to your camera. Now
you can start photography.
