OK, I was given a field vision telescope as a gift. model #F700/76.
The is a very small operationinstruction manual with it that covers pretty much nothing.
Having never had a telescope before, I have no idea why the images I view are upside down. I assume they are not supposed ot be... how does one correct this? Is it missing a lens or am I doing something wrong?
As we all learned in grade school, telescopes produce an upside down image - it's okay for astronomical use since upside down doesn't matter. If you want an image like you'd see in a pair of binoculars, get an image erector from a telescope accessory store to add to your eyepiece.

well this is a common complaint amoung ameteur astronomers who have just gone out and bought themselves a reflecting telescope ie the type that uses mirrors. the thing is when the light is gathered it comes in at different angles and goes through a sort of "overtaking" process when it hits the primary mirror then is bounced onto the secondary mirror (this should be aligned at 45 degrees) and then in to the eyepiece. so getting to the point you are not alone and this is what happens in all reflecting scopes and you can correct this with about $10000 US i think this method involves using complicated camera optics but there may be simple eyepieces and filters that you could buy to solve the problem. i don't know how to correct the problem but i know what it is and how to explain it.
kind regards

In your telescope kit (I have one as well)there should be 2 long tubes that fits in the eyepiece socket on the telescope. One of these is the erector lense that will flip the images for you. Eben

I can not get the Barlow lens of my model 60050 to focus. The other smaller lenses focus fine. I have tried zoom in and out using the focusing system, but all I see is a continuous blur. I inspected the Barlow lens to see if it was complete, and noticed that it has one lens towards the tapered end only. Is this how it should be...
I wanted to use the telescope to look at the city, buildings and near by objects. I was able to see images correctly and then after I cleaned the lens on the telescope I was no longer able to see the images correctly. They appeared up side down!
