Your new Levenhuk Ra ED Doublet OTA is ready for observations right out of the box. This user guide will provide useful
information on assembling your optical tube and various accessories, so that you can begin your journey through the celestial
sphere with ease.
Note! A mount, tripod, diagonal mirror, diagonal prism, eyepiece, eyepiece adapter, nderscope and nderscope
base, extender, photo adapter, T-ring and camera are not included in the kit.
Finderscope, star diagonal and eyepiece assembly
• Attach the nderscope base onto the optical tube. Loosen the thumbscrew on the base. Install the nderscope onto the
base. Retighten the thumbscrew.
• All optical tubes accept 2" accessories (some models may require the use of a corresponding adapter with 1.25" or 2"
accessories). Keep in mind, however, that your views will be out of focus without a star diagonal or an extension ring.
To install a star diagonal or an extension tube, simply loosen the thumbscrew on the side of the focuser, insert the
accessory, and retighten the thumbscrew. Afterward, you can insert the desired eyepiece into the already attached star
diagonal or extension ring.
Attaching the OTA to a mount
Your OTA is tted with a mounting bracket (quick-release screw connectors) that may be used to attach the optical tube to a
mount or to another OTA as a guidescope.

Levenhuk Ra ED Doublet OTA
Congratulations on your purchase of a high-quality Levenhuk telescope! These instructions will help you set up, properly use, and
care for your telescope. Please read them thoroughly before getting started.
Your new OTA has an extremely fast focal ratio that makes it perfect for wide-eld astrophotography, yet it still produces
breathtaking views during visual observations. All optical elements are made of high-quality ED glass with extra-low dispersion
and are fully multi-coated for crystal clear and sharp views across the eld of view with no chromatic aberration.
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.
CAUTION! Never look directly at the Sun — even for an instant — through your telescope or nderscope without
a professionally made solar lter 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 nderscope is covered with aluminum
foil or another non-transparent material. Children should use the telescope under adult supervision only.

Operating the telescope
Focusing
During celestial observations, out-of-focus images of dim stars may be very diuse, making it dicult to focus on such objects.
Choose a brighter celestial body (such as the Moon) as your rst observation object, and focus your view. With a 10:1 ne focus
adjustment (meaning that 10 turns of the ne focus knob equal 1 turn of the coarse focus knob), you can adjust the focus of
your view with great precision. Use the coarse focus knob to adjust the view until your object is as close to focus as possible,
and then make ne adjustments with the ne focus knob.
Eyepieces and magnication
An eyepiece magnies the image produced by the OTA. The longer the focal length, the lower the eyepiece magnication, and
vice versa. Therefore, it is recommended to have several eyepieces in your equipment. The total power of the telescope setup
may be calculated with the following formula:
Magnication = Focal Length of Telescope (mm) / Focal Length of Eyepiece (mm)
