Orion SpaceProbe 130ST EQ We cannot use the telescope because we cannot focus the 25mm Sirius Plossel eyepiece. When we look through the eyepiece, we see nothing. What should we do? Thank you.

Doubtful you will find the exact manual as these are made in India. However this is very similar in operation and assembly to several other brands. Take a look at this video-

These are simple to assemble and use once you have seen it done. Try to find a local Astronomy club whose members will help you with the scope.

Those are called defrraction spikes --- and really do not affect the view. Stars are always just points of light.

Make sure the scope is collimated- watch this video:

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.

That all depends on what telescope it is, but generally you line it up with whatever you are trying to view, then you start with the biggest eyepiece you have (say you have a 9mm, 12mm, and 24mm; you should always start off with the 24mm) then gradually bring the mm size til u get to your lowest or however far you need to zoom into

Depends on the distance from the ground to the eyepiece. I use a step stool that has three steps and a platform on top - and still have to stand some times. Stand, sit, the scope don't care either way...

It's not in focus--- turn the focus knob slowly in and then out until you get a sharp image....... use the lowest magnification eyepiece first-- that's the one with the LARGEST number written on it.

Not upside down---

The eyepiece and focuser is on the FRONT of the telescope. Light enters the tube-- hits the mirror on the bottom-- and bounces back up to the small secondary mirror which reflects it out to the eyepiece.

It's called a Newtonian design--
