Celestron PowerSeeker 50AZ 21039 Manual

1. Unpack your telescope and verify that all parts are present. Your PowerSeeker 50AZ includes: optical tube w/ lens shade attached; tripod with center support bracket and accessory tray; three eyepieces; a 3x Barlow lens, star diagonal, finderscope with bracket, and a 1.5x image erecting eyepiece.
   
2. To set up the tripod, spread the legs outward until they are fully extended and push down center leg brace.
   
3. Extend the center portion of each of the three tripod legs down about 6 to 12 inches. Flip the tightening lever inward on each leg to secure the extended leg in place.
   
4. Check to ensure that all three legs are the same height once extended to provide a level platform for the telescope.
   
5. To mount the accessory tray, remove the fastener from the lower support bracket.
   
6. Place accessory tray on lower support bracket and then tighten fastener.
   
7. Remove the threaded bolt from the underside of the telescope tube.
   
8. Line up the hole in the mount with the holes on the underside of the optical tube as shown above.
   
9. Replace the threaded bolt to secure the optical tube to the mount.
   

10. Properly assembled the optical tube should appear as pictured above.
    
11. Remove the knurled finderscope nuts from the optical tube.
    
12. Orient the finderscope so that it is facing towards the front of the tube. Place the finderscope over the screws as shown.
    
13. Replace the knurled nuts to secure in place and remove the lens covers.
    
14. Loosen the set screws on the focuser and remove the plastic cap.
    
15. Insert the diagonal into the focuser and tighten the set screws to secure in place. Remove the plastic cap on the diagonal.
    
16. Place the 20mm eyepiece into the barrel of the diagonal as shown above. Tighten the set screw to secure in place.
    
17. Remove the lens cap from the front of the telescope.
    
18. To observe, look through the eyepiece as shown above. Focus the image by turning the knobs below the focuser.
    
19. 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.
    
20. Insert the barrel of the 20mm eyepiece into the Barlow lens and tighten the screws to secure it in place.
    

1. 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.
   
2. 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.
   
3. LOOK THROUGH FINDERSCOPE
   Once the object is centered in your 20mm eyepiece, look through the finderscope and locate the crosshair reticle.
   
4. 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.
   
5. YOUR FINDERSCOPE IS NOW ALIGNED!
   It should not require realignment unless it is bumped or dropped.
   

1. With the Moon visible in the sky, set up your telescope with the 20mm eyepiece installed.
   
2. Move the telescope so that it is roughly pointing toward the Moon.
   
3. Look through the finderscope and locate the crosshair reticle. Continue moving the telescope until the crosshair appears over the Moon.
   
4. Look through the telescope's 20mm eyepiece. Gently turn the focus knobs to adjust the sharpness of the image.
   
5. CONGRATULATIONS! YOU HAVE NOW OBSERVED YOUR FIRST CELESTIAL OBJECT! 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.
   
6. 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.
