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 exing 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 ngers. 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 (g. 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 magnication.

• Look through the eyepiece and focus your view by rotating the coarse focus ring.

• Precise focus adjustments may be done with the ne focus ring. Now you can start observing.

As a camera objective lens (g. 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.
