I need to know how to assemble the eyepiece on a Bushnell 565 telescope?


The eyepiece DOES NOT assemble. It is all one piece. If you unscrew the bottom or the top-- never do this. You must reassemble the lenses exactly.

The eyepiece goes directly into the diagonal (an L shaped device with a mirror inside, and then the diagonal goes into the tube.. That's it. You can buy eyepieces from dozens of different suppliers. Here is one:

Hi, I own a Bushnell Deep Space Model 78-9518. One lens fell off, and I have no idea from where. Does anyone have a description of the lenses for this model? Thank you.


You mean an eyepiece fell out? Or one of the two mirrors inside the scope?

Eyepieces are sold by many different retailers even amazon.com has them. They come in three sizes .965 inch, 1.25 inch, and 2 inch, measure the hole in the focuser and buy the correct size.

Other than Amazon.com here is another retailer:

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.

I TOOK THE EYEPIECE APART TO CLEAN IT AND HAVE THE LENSES OUT OF ORDER, WHAT IS THE CONFIGURATION OF THESE LENSES? CELESTRON 114.


NEVER EVER disassemble an eyepiece --- no one can tell you how the lenses go together there are dozens of combinations and some eyepieces have as many as 6-8 glass lenses inside!

Sorry buy another eyepiece and only clean the outside surfaces.

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?

Lens' in my new Voyager 78-9960 telescope fell out


The small squares are spacers between the lens elements. Most objectives have 2 parts, with one lens like() or (|. That is the one on the outside, with the outwardly curved side facing the object to view. The other lens goes behind it, making the stack look like: (object) --- ())| for the 2 lenses. Sorry, this page does not allow proper graphics, but I hope you get the idea.
Do not tighten the retaining ring too tight - just enough to hold in place. The lenses need a little space for thermal expansion.

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
