Put the eyepiece with the largest number written on it into the focuser. This is your lowest magnification.

During the day time point the scope at a distant object and practice focusing -- you may need to turn the focus knob several times right or left to achieve focus.

It will focus if you turn the knob enough.

Cant get an image.Is it right that the view finderimage is upside down

The image of all astronomical telescopes are upside down (SCTs are upside down and reversed). RACI (right angled, correct image) finders do produce a right-side up image. For daytime use a erect image prism eyepiece.
Follow below instructions (except 7 in your case)

  1. Get Stellarium or another fine astronomy program
  2. During the day, point the telescope at a part of the landscape about 100 yards away.
  3. Use the lowest power eyepiece (highest number) in the focal tube.
  4. Center the landscape object in the telescope.
  5. Align the finder scope so that it points exactly where the main telescope is.
  6. At night, leave the scope out to reach thermal equilibrium (about an hour for small reflectors and refractors)
  7. If the scope is on a EQ mount, polar align.
  8. Point the finder at the moon. The moon should be in the main scope also.
  9. Practice finding the moon before you start on the planets
  10. Once you are comfortable with the moon and planets, you can go for the deep sky objects

No image viewed through the eyepieces of telescope

hi Bienfechiva.
this is all i could find from the internet.
( Put the eyepiece with the largest number written on it into the focuser. ... Turn the focus knob back and forth slowly until the image is in sharp focus.)
as you say you have the manual so no point it sending you to that link.
so go to this link and see if it helps.

Cant see anything through the view finder

1. During the day, use the 17mm eyepiece on a object outside (telephone pole, water tower, etc) then align the finder to what you see in the scope.
2. Put in the 7.5mm eyepiece and fine align the red dot finder.
3. At night, point the finder at the moon (less than half moon or the image is too bright without a moon filter) Use the 17mm eyepiece.
4. Once you see the moon, switch to the 7.5mm lens and enjoy.
5. Download Stellarium or any free astronomy software and see what is in your sky tonight. Your scope should be able to see Jupiter and its moons easily.(Saturn, Mars and Venus when the time is right) Open clusters like Pleiades will be nice is this fast scope.
5. If stars are not sharp, you may need to collimate the scope. Look online for general instructions.

We just set up our telescope and can't see anything. We do have the cover off, have used all the eye pieces but it's dark. Kinda feel like a dope but obviously we're missing something. ...

Start by using it during the day pointing at a nearby object (100yds or so) Start by sighting along the axis of the scope. Use the lowest power (highest number in mm) eyepiece. (BTW the eyepiece is in the front of the scope where the light comes in and this will be the part of the scope that is closest to the object) Once you can see the object, move to the higher power eyepiece to center on the object and then align the led pointer so the red dot is also centered on the object.
After this initial alignment, pick a night that the moon is out and try it.
Note: The 114 shows correct image (right side up and left to right) unlike most other scopes. It is a nice telescope/ ( I have the 130mm)

After i remove all the appropiate lens caps and align the red dot, i cant see anything out my lens except darkness. Total black background,day and night. Should i try something else,thanks.

Put the eyepiece with the largest number written on it into the focuser, do not use the 2x barlow. TRY AGAIN-- during the day time and practice focusing on a distant object.

The end with the FOCUSER is the UP end of the tube-- the mirror is on the bottom of the tube. Many beginners mount these BACKWARDS.

Lost my manual

You have a 60mm refractor telescope on an equatorial mount. First the mount must be polar aligned in order to useit. Second I believe these take .965 eyepieces. Most amateur scopes use 1.25 inch eyepieces,

The eyepieces are very cheaply made. Some may also have plastic lens instead of high quality glass, and they are not muti-coated lenses.

Why am I saying all this? because this scope will frustrate you. The tripod is shaky and the connection between the mount and the scope tube is never solid. The scope will not stay pointed and it will be difficult to move it around the sky accurately. Sky objects are very tiny. Less than the tip of you finger held at arms length!

We never recommend an EQ mount to a beginner, and never recommend a 60mm telescope. You could have bought a pair of 10x50mm binoculars and they would have been much better for astronomy.

The manual will NOT teach you how to polar align the scope or how to find objects in the sky.

Read my TIPS on my profile page Frequently Asked Questions, and also the one on aligning an equatorial mount on the star Polaris.

This is the only manual I have ever found-- someone took images of the manual and posted it on-line-

I don't know how to use the motor and the image is upside down

All astronomical telescopes have upside down images. No up more down in space, and MORE glass is needed to erect the image which decreases the light.

If your scope is like the one in the picture it is an equatorial mount which must be polar aligned to work. Once the scope is roughly polar aligned the motor will keep the object in the eyepiece for a long period of time. It moves the RA axis in time with the movement of the stars across the sky.

Red dot finder scope

Simple-- you can also do this during the day on an object at least 100 yards away-- but at night; get the moon centered in the eyepiece and without moving the telescope center the red dot on the moon. This will get you almost aligned-- then put a bright star in the eyepiece and readjust the red dot to center the star.

Just black

Just a dumb question - but did you place the eyepiece in the focuser? Start with the largest - it has a wider field of view to get started.

GoTo Problem

Be sure that the telescope is configured for EQ SOUTH mode to tell it is in the southern hemisphere. Once a star alignment is completed NEVER manually move the telescope. Use only the control panel to slew. Everytime the telescope is move by hand, the motors do not know it has been done, and assume it is still pointing at the old direction. Check the manual for setup.
