Note: Before assembling tripod legs to Altazimuth Yoke Mount, make sure the Accessory Tray Braces (8) face inward. Locate the long bolts and washers from the hardware pack. Position the mount over the Tripod Leg (6) as shown (ﬁg. 1). and align the holes in the Tripod Leg with the holes in the mount. Insert the bolts through the holes at the top of a Tripod Leg. A washer should be positioned on both outer sides of the Tripod Leg. Attach a wing nut to the bolt, but do not tighten it all the way. Repeat on the remaining two Tripod Legs. Once you have attached all Tripod Legs to the mount, securely tighten all wing nuts. Remove the Stabilizer Bar Mounting Screw (11) from the hardware pack and insert it into the opening at the base of the Vertical Stabilizer Bar (4).

• Locate the Accessory Tray (9). Using the accessory tray bolts, wingnuts and washers connect the Accessory Tray to theAccessory Tray Braces (8). Start with one tripod leg and attach wingnuts. Wingnuts should be positioned beneath the accessory tray. Do not tighten wingnuts until all Accessory Tray Braces are attached as some adjustments may be required.

HOW TO USE YOUR NEW TELESCOPE
Astronomical telescopes are designed such that the image you see will appear UPSIDE DOWN and REVERSED, this is acceptable for viewing celestial bodies. However, this special telescope offers an Erect Image Eyepiece which will deliver a 30x view that will NOT BE UPSIDE DOWN or REVERSED. This 30x eyepiece is recommended for viewing
either land or night sky based objects.
Using your Eyepieces:
1.You should always start viewing with the lowest power eyepiece, which in this case is the 30x lens. This 30x erect image eyepiece is unique and will correct images to appear right side up as you view them through the telescope. This is especially beneﬁcial when viewing objects on land. Note: While images will not be upside down, they may appear tilted slightly. This apparent tilt is due to your viewing position with relation to the telescope. Depending on where you place your eye, the image tilt will vary. The important feature of this eyepiece is that the image is right side up and correct left to right (not a mirror image).This eyepiece is recommended for either land or sky viewing.
2.The 4mm lens is a traditional telescope eyepiece and will provide an image that on land will very clearly deliver an image that is upside down. However, this is normal and becomes unimportant as you view objects in the night sky. This eyepiece is recommended for sky viewing only.
1.After selecting the desired Eyepiece (3), aimMain Telescope Tube (14) at a
200yards away (e.g. A telephone pole or building). Fully extend focusing tube by turning Rack and Pinion
Focusing Mechanism (2).
2.While looking through selected Eyepiece (3) (in this case the 30x), slowly retract focusing tube by turning
Rack and Pinion Focusing Mechanism (2) until object comes into focus.
Aligning and Using Red Dot Finderscope:
1.Remove plastic insert on bottom side of ﬁnderscope to allow battery to make connection with battery contact for power. Turn power switch on.
2.Look through main telescope tube at low power and establish a
Never Look Directly At The Sun With Your Telescope Permanent Damage To Your Eyes May Result.
Enjoying Your New Telescope
1.First determine your targeted object. Any bright object in the night sky is a good starting point. One of the favorite starting points in astronomy is the moon. This is an object sure to please any budding astronomer or experienced veteran. When you have developed proﬁciency at this level, other objects become good targets. Saturn, Mars, Jupiter, and Venus are good second steps to take.
2.The ﬁrst thing you need to do after assembling the telescope as planned is center the desired object in the ﬁnderscope. Provided you did a reasonable job aligning the ﬁnderscope, a quick look through the main telescope tube at low power should reveal the same image. With the lowest power eyepiece (the one with the largest number printed on it) you should be able to focus the same image that you saw through the ﬁnderscope. Avoid the temptation to move directly to the highest power. The low power eyepiece will give you a wider ﬁeld of view, and brighter
3.The low power eyepieces are perfect for viewing the full moon, planets, star clusters, nebulae, and even constellations. These should build your foundation. However, for more detail, try bumping up in magniﬁcation to higher power eyepieces on some of these objects. During calm and crisp nights, the light/dark separation line on the moon (called the “Terminator”) is marvelous at high power. You can see mountains, ridges and craters jump out at you due to the highlights. Similarly, you can move up to higher magniﬁcations on the planets and nebulae. Star clusters and stars are best viewed through the low power no matter what.
4.The recurring astronomical theater we call the night sky is an
1.Your telescope is a very sensitive instrument. For best results and fewer vibrations set your telescope up on a level location on the ground rather than your concrete driveway or your wooden deck. This will provide a more stable foundation for viewing, especially if you’ve drawn a crowd with your new telescope.
2.If possible view from a location that has relatively few lights. This will allow you to see much fainter objects. You’d be surprised how much more you’ll see from your local lake or park when compared to a backyard in the city.
3.Using your telescope out a window is NEVER recommended.
4.View objects that are high in the sky if possible. Waiting until the object rises well above the horizon will provide a brighter and crisper image. Objects on the horizon are viewed through several layers of earth’s atmosphere. Ever wonder why the moon appears orange as it sets on the horizon. It’s because you are looking through a considerable more amount of atmosphere than you would directly overhead. (Note: If objects high in the sky are distorted or wavy, you are probably viewing on a very humid night.) During nights of unstable atmosphere, viewing through a telescope can be frustrating if not impossible. Astronomers refer to crisp, clear nights as nights of “good seeing.”

ANSWERS TO COMMONLYASKED QUESTIONS
The image I see in the telescope appears tilted
This is natural and due to the position of the eye
when using the 30x Erect Image Eyepiece
in relation to the telescope tube. The real beneﬁt of the
eyepiece is to deliver an image that is able to be used
when viewing on land.
How do I determine the power my telescope ?
The power of your telescope can be determined
by dividing the focal length of the objective lens by the
focal length of the eyepiece. The eyepiece focal length
is the number printed on the eyepiece. (For example:
700 / 25 = 28X)
Where do I ﬁnd the Telescope Focal Length
The telescope focal length is the same focal
length as the objective focal length. For this telescope it
is 700mm. Telescope focal lengths range from 600mm
to 900mm on most telescopes.
What can I see with my telescope ?
Telescopes with power ranging from 25X to
50X can be used to view Star Clusters and Nebulae.
90X to 120X telescope can view galaxies. Most planets
can be seen at 150X and higher.
What do the numbers on the eyepiece mean ?
The numbers on the eyepiece represents the
“focal Length” of the eyepiece.
If after you have

number) eyepiece to begin viewing.
