We had the 20mm eye piece in and we turned the focus all the way clockwise so the eye piece was all the way in. We had the cover off, we had a very clear starry night, we live in the country, moved the scope around for 20 minutes, trying to find any star, and could not see anything...did we do something wrong? When you are looking through the star finder with the LED, so you psotion your head behind the scope barrel and try to put the star in the LED or do you 6" away or where, because as I moved my head, the site changed. By using the scope in the daylight, looking at an object and focusing it in, how does that correspond to us being able to use it at night? We are excited to use this, but are frustrated .... thanks for your help.

Sounds like you've dislodged one of the prisms inside. A service center can look it over for you, but from personal experience, it's cheaper to replace them than pay to ship them to/from the service folks plus the estimation fee just to find out that they'll have to be replaced, anyway. Sorry.

The smaller the number THE HIGHER the magnification.

It depend on the eyepiece anywhere from 10-20mm away.

Put the eyepiece with the largest number written on it into the focuser. DO NOT use the 2x barlow -- practice focusing on a distant object during the day time.

Typically the left eye piece is not adjustable. You focus the left eye with the center adjustment and then focus the right eye with the eye piece adjuster. I hope this helps.

check how big the scope lenses are and have a look on e-bay there are lots of covers on there

Put the eyepiece with the largest number written on it into the focuser-- try again. You may need to make several turns of the focuser knob to get into focus.

It is common for binoculars to have one independently focusable eyepiece.  If one eyepiece can be rotated, then that is the case.
If that is the case, focus through the one that DOES NOT rotate using the center control until you get a sharp image on that side.  Then rotate the eyepiece on the blurry side until the blurry side is sharp.  If you succeed at this, from henceforth the center control will focus both eyes adequately

You need a DIAGONAL see this picture, it's basically an "l" shaped accessory that fits into the end of the telescope so you look DOWN into the eyepiece.

I'm surprised it did not come with the 20mm eyepiece. That is a good all-around eyepiece that works well for viewing across the bay or looking at the Moon. You may also want to get a barlow to "right" the Earth based images.

I recommend purchasing a 20mm eyepiece for your viewing pleasure. I hope this FixesYa!

Hello,
What you have is called a refractor-type telescope with the primary lenses (the Objective) at the top of the tube and the only other lenses in the system are your selection of eyepieces, probably a barlow lens (2X magnification of any eyepiece used), and a diagonal (in line mirror so that you cand see into the telescope from the side.). As the focal lenth of the eyepiece decreases, so does the distance away from the Objective Lens. I believe that you are using the telescope with a diagonal mirror which makes the optical path longer. The fact that your longer focal lenght eyepiece can focus and not your short one would be only if you didn't have the diagonal or the eyepiece all the way in tight to allow the focus mechanism (rack and pinioin) to get compressed enough to focus. Look at the Moon, if the image gets smaller then bigger as you focus, but not sharp, then I would have to tell you that your eyepeice lenses are not in the right order. Someoner may have taken it apart and didn.t put them back in the correct order. The lenese could just be very dirty also. Barrow a short focal lenght eyepice from a friend and see if it works in your system. Then you will know for sure.
