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--

No image through lenses

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!

Comone end has a cap on it, the other is blanked off. looking thro side viewer is black. I have no idea & no instructions so please can you help!

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.

Hello... I'm kinda new to all this, so please bare with me! I recently purchased a used Orion Skyview 6 Deluxe EQ. The scope is in great shape and things look great through it. However, it did not...

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.

Hi, i saw you offered to send the manual for the optisan star 70076 to someone and wondered if you would do the same for me. my email address is or

You posted this question directly on Fixya. The manual will only have assembly instructions, it will not tell you how to use the scope to find objects in the night sky.

Better to buy two books and do some reading.

Does the Celestron AstroMaster 114EQ use a diagonal?

NO, you do not need a diagonal. The eyepiece goes directly into the focuser.

images in astronomical telescopes are always INVERTED-- you can buy an "erecting prism diagonal" for terrestrial viewing, but it is not needed for star gazing.

Image is upside down (inverted)

All astronomical telescopes show upside down images this is normal.

You can buy an "erecting prism" to use for terrestrial viewing from many on-line retailers here is one: This will flip the image so it is not upside down.

How to focus telescope lens for city viewing?

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.

The erecting prism can be used for both terrestrial and star gazing-- put it innto the scope first.

The 3x barlow probably will NOT be very useful... it triples the power of any eyepiece. Your small scope cannot go much over 100 power-- before the image degrades.

Put the eyepiece with the BIGGEST number written on it into the erecting prism which you previously stuck into the scope... now go outside during the daytime and practice focusing on a distant object.

The bigger the number on the eyepiece the LOWER the magnification.
