Celestron PowerSeeker 70EQ - Telescope Quick Setup Guide

How to use

Unpack your telescope and verify that all parts are present. Your PowerSeeker 70EQ includes: an optical tube; tripod; equatorial mount; latitude adjustment screw; star diagonal; 2 eyepieces; a 3x barlow lens; finderscope; 4 lb. counterweight; counterweight bar; two slow motion control cables; and an accessory tray.
To set up the tripod, spread the legs outward until they are fully extended and push down center leg brace.
Extend the center portion of each of the three tripod legs down about 6 to 12 inches. Use the tightening screw on each leg to secure the extended leg in place.
Check to ensure that all three legs are the same height once extended to provide a level platform for the telescope.
Place the eyepiece accessory tray on top of the tripod's center leg brace. Thread the tray into the the threaded hole in the center of the leg brace until it is fully seated.
If necessary, rotate the accessory tray counterclockwise until the accessory holes are not covered by the leg brace arms as shown here.
Locate the equatorial mount and place the base of the mount through the hole in the center of the tripod mounting platform.
From underneath the tripod mounting platform, thread the attached mounting bolt into the hole on the bottom of the equatorial mount.
Look up the approximate latitude of your observing site on the Internet or using a map. Then, thread the latitude adjustment screw into the equatorial mount until your latitude is indicated on the latitude scale.

Locate the counterweight bar and counterweight. Slide the counterweight half way down the counterweight bar.
Holding the counterweight in one hand, line up the counterweight bar with the mount. With your other hand, turn the counterweight bar until it is fully seated. Tighten the counterweight locking screw to hold the counterweight in place.
Slide the chrome end of the slow motion control cables onto equatorial mount gear shaft. Be sure to line up the set screw over the flat spot on the shaft. Tighten screw to secure in place.
The cable should attach to the Right Ascension axis and the other cable attaches to the Declination axis. Tighten the screw to secure the cable in place.
Remove the tube rings from the telescope tube by loosening the latch knobs on the sides of each ring. Then remove the two knobs on the bottom of each tube ring.
Insert the tube rings into the holes on the top of the mount and secure them using the knobs you removed from the bottom of each ring.
Place the telescope tube back into the tube rings and secure the latch knobs to hold it in place. The front of the tube should be positioned over the counterweight assembly.
Remove the knurled nuts on the threaded posts at the focuser end of the telescope tube.
Locate the finderscope and remove plastic caps on front and back of lens. Orient the finderscope so that the larger lens is facing towards the front of the tube as shown here. Place finderscope over the holes on the tube and tighten it down with the knurled nuts.
Loosen the screws on the focuser so they do not obstruct the inner diameter of the focuser. Remove the plastic cap covering the end of the focuser. Insert diagonal into the focuser and tighten the set screw.
Remove cap and insert the 20mm eyepiece into the diagonal and tighten the set screw.
Remove the lens cap from the front of the telescope. To observe, look through the eyepiece as shown above. Focus the image by turning the knobs below the focuser.
For additional magnification, you can use the included 3x Barlow lens. Place the Barlow lens in the focuser in place of the eyepiece. Remove the cap from the Barlow lens.
Next, insert the eyepiece into the Barlow and tighten the set screws to secure it in place.

SOLAR WARNING: Never attempt to view the Sun through any telescope without a proper solar filter.

ALIGNING THE FINDERSCOPE

The finder is one of the most important parts of your telescope. It helps you locate objects and center them in the eyepiece. The first time you assemble your telescope, you need to align the finder to the telescope's main optics. It's best to do this during the day*.
*
SOLAR WARNING!
Never attempt to view the Sun through any telescope without a proper solar filter!

CHOOSE A TARGET
Take the telescope outside during the day and find an easily recognizable object, like a streetlight, license plate or sign. The object should be as far away as possible, but at least a quarter mile away.
CENTER THE TARGET IN THE EYEPIECE
Look through the telescope using your lower powered 20mm eyepiece. Move the telescope until the object you chose lies in the center of the view. If the image is blurry, gently turn the focus knobs on either side of the telescope until it comes into sharp focus.
NOTE: The image in your telescope may appear inverted. This is perfectly normal in an astronomical telescope.
LOOK THROUGH FINDERSCOPE
Once the object is centered in your 20mm eyepiece, look through the finderscope and locate the crosshair reticle.
ADJUST THE FINDERSCOPE
Without moving the telescope, use the three finger knobs surrounding in the finderscope bracket to move the finder around until the crosshair appears over the same object you are observing in the telescope's 20mm eyepiece.
TIP: Try adjusting one screw at a time. Loosen one screw by half a turn and tighten another by the same amount to ensure the finderscope is securely held in place.
YOUR FINDERSCOPE IS NOW ALIGNED!
It should not require realignment unless it is bumped or dropped.

YOUR FIRST NIGHT OUT THE MOON

The best and easiest target for you to try to view first is the Moon. Try observing the Moon at different points in its phase cycle. The best time to view the Moon is from two days after a New Moon up to a few days before a Full Moon. During this period, you will be able to see the most detail in the craters and lunar mountain ranges.

With the Moon visible in the sky, set up your telescope with the 20mm eyepiece installed.
Move the telescope so that it is roughly pointing toward the Moon.
Look through the finderscope and locate the crosshair reticle. Continue moving the telescope until the crosshair appears over the Moon.
Look through the telescope's 20mm eyepiece. Gently turn the focus knobs to adjust the sharpness of the image.
To get a closer view of the Moon, loosen the set screws on the focuser and remove the 20mm eyepiece. Replace it with your 4mm eyepiece and tighten the set screws to secure it in place. The 4mm eyepiece will give you significantly more magnification, making the Moon appear much larger.
NOTE: You may need to adjust the focus knobs when you change eyepieces, so make sure you are getting the sharpest image possible.
You can view many other celestial objects, such as planets, star clusters and nebulae using this same technique if you know where to find them in the night sky.
