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 scopelevenhuk-FT72-ED0-PhotoScope-
FIG-1

  • 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.
