I have a bushnell 18-1560 telescope the 2 lenses have come out and I'm not sure which one goes in first, can you help me out on this , thanks


Sorry-- no we cannot help you. NEVER remove the front lenses from a telescope. Only the outside surfaces would ever need to be cleaned.

You will need to experiment-- there are really only a limited amount of possible ways to assemble two lenses together. Try each different way -- and use cotton gloves so you do not get fingerprints on the lenses.

While moving from NYC to Ft. Lauderdale, Fl, it seems that a lense was displaced inside my telescope. How can I fix this problem?


This telescope does NOT have a lens it has MIRRORS.

It also has eyepieces that slip into the focuser on the side of the tube.

Did you loose your eyepieces? or did the mirror fall out?

A telescope like that has a very narrow depth-of-field, so you need to focus very, very slowly to be able to see any image. Try focusing on something bigger (like a spot on the moon) and adjust the crosshair accordingly. The two eyepieces gives different magnification.

Images viewed are upside down


oh this is normal,because when looking at stars it really doesnt matter if they are inverted,but by leaving out the erecting lenses you get more light and less distortion. so you need an erecting lense to see images in the daytime,call bushnell@18004233537,im sure they can sell you the right adaptable piece....good luck...larry@reichinstruments.com

Not worth repairing-- a new focuser for your telescope would cost as much or more than the telescope-- unless you can find a discarded telescope of the same model..... for parts.
