Re: optisan star 70076
Try the other eyepiece first-- no one can fix that scope which is imported. No repair facilities or replacement parts. Next time stay away from those types of scopes-- buy from one of these NORMAL scope retailers--

1. During the daylight point the telescope towards an object (water tower, building ) something about 1/2 mile away. 2. Locate the object in your finder. 3. Use the 12.5mm lens (50x) and look through the telescope. Do not use the erect prism 4. Align the finder to what you see in the scope. 5. You can use the 4mm to fine adjust the finder. 6. On a good, clear night.Leave the scope out to reach thermal equilibrium ( about a hour) Point the finder towards the moon 7. Use the 12.5mm and then focus on the moon.
Note: This is NOT a quality scope. Avoid any scope with .965 eyepieces and silly magnifications! Max power on this scope on a PERFECT night is 200x and Huygens (H12.5) eyepieces give very narrow and poor viewing. Do not use the 3x barlow or the erecting prism. the erecting prism is for terrestrial viewing only and the barlow, although it increases the eyepiece by 3x, will also narrow the view. Good Luck!
Remove the cap and put an eyepiece into the focuser on the side of the tube. Turn the focus knob until you get a sharp image. Do this in the daytime on a distant object like the top of a telephone pole.
Use the eyepiece with the largest number written on it until you learn how to focus properly.
First WHY would you use a erecting DIAGONAL in a reflector style telescope. Upside down images are completely normal for an astronomical telescope. You only need this diagonal for terrestrial viewing NOT for star gazing. ALL astronomical telescopes show upside down and or inverted images- it's completely normal.
If you cannot come to focus with the erecting diagonal, it's probably because the diagonal moves the eyepiece too far OUT away from the point where the scope comes to focus. Again-- you do not use those for night time sky viewing. Just stick the eyepiece directly into the focuser.
No no manuals. The smaller the number written on the eyepiece the GREATER the magnification.
However many astronomical telescopes show everything upside down. This is normal -- no up or down in space. You can buy and erecting prism diagonal for terrestrial viewing which will turn the image right side up.
