You never told us what model number or telescope TYPE you own. Is this a refractor or a reflector. ???

If a REFRACTOR usually you have a diagonal, the diagonal goes into the focuser and then the eyepiece goes into the diagonal.

On a REFLECTOR the eyepiece goes directly into the focuser.

SOURCE: Cannot see through the lens of a 565 bushnell telescope

Did you remove the lens cap.

This is a simple refractor telescope. Put the eyepiece with the largest number written on it into the telescope. DO NOT use the 2x barlow if you have one.

Practice focusing on a distant object during the day time. Read my TIPS on my profile page.

hi there koosie when using the 4mm eye piece you have to be looking at something at quite a distance hence the power with a 20mm eye piece you can focus closer objects and dont need so much light as the 4mm the more power the more light and furthur away the least power(20mm)the least light and closer you cant focus close with a 4mm eye piece but can with a 20mm

The erecting prism can be used for both terrestrial and star gazing-- put it innto the scope first.

The 3x barlow probably will NOT be very useful... it triples the power of any eyepiece. Your small scope cannot go much over 100 power-- before the image degrades.

Put the eyepiece with the BIGGEST number written on it into the erecting prism which you previously stuck into the scope... now go outside during the daytime and practice focusing on a distant object.

The bigger the number on the eyepiece the LOWER the magnification.

SOURCE: Bushnell 114mm reflector telescope, can't see a thing

Probably NOT actually pointed directly at the moon-- you should have moved it around a little -- the moon was probably just outside the field of view through the eyepiece. ........................ telescope must be pointed DIRECTLY at the sky object-- also use the eyepiece with the largest number written on it=== this gives the LOWEST magnification..... and a slightly wider field of view.

SOURCE: I have the bushnell telescope

if it's a reflector telescope (a mirror on one end of the tube and an open end on the other), you point the open end of the tube at your target.
or you might need to collimate your telescope. sky and telescope's websit shows you how to do it. it's under the 'Do-It-Yourself' section (left side of page).

hope this helps :D

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:

We just got our Bushnell Voyager 78-9945 Reflector Telescope. It comes with the poorest manual I have ever seen. How do you assemble the eye piece?, what is the little shiny metal triangle piece for? Does...


I think I already answered this question. Eyepieces are NOT assembled they are one piece like this picture:
http://www.amazon.com/Celestron-93342-17MM-Plossl-Eyepiece/dp/B000YKZKNI

They simply slip into the hole of the focuser -- straight in. The larger the number written on the eyepiece the LOWER the magnification.

In the picture above there is a metal triangle holding the tripod legs apart-- it is called a "tripod spreader" or a tripod "tray"-- used for holding eyepieces and other small pieces of equipment while you are using the scope.

Hope that helps you.

Bushnell 78-9003 telescope purchased at yard sale with no eyepiece. Where can I purchase one that will fit? It talks about a .965 inch eyepiece.


.965 eyepieces are readily available on ebay. A meade 25mm MA (modified achromat) is about $10 plus shipping This will give you 700mm/25mm= 28x power. Avoid any eyepiece marked with a H (Huygens) as they have terrible field of view.
.965 is not a popular size anymore and Bushnell does not make very good telescopes. Don't get frustrated, if you are still interested, buy a Meade, Celestron, Orion quality telescope.

We are unable locate a manual for a Bushnell telescope 78-4620B. cn yoiu direct us pleaase?


All of Bushnell's manuals are on this web site:
http://www.opticsplanet.net/bushnell-warranty.html

Remember that the manual will only have assembly instructions. It will not teach you how to focus, what eyepiece to use, or how to find objects in the night sky.

Locate a local astronomy club and the members will help you once you have assembled the telescope.

What is the lens arrangment in the eyepiece of an 18-1560?


Did you DIS-assemble the eyepiece? If you did no one can tell you how to put it back together.There are so many different eyepieces. Normally the eyepieces just slip into the focuser.

Eyepieces are either .965 inch or 1.25 inch in size. Measure the hole. You can buy eyepieces from many on line astronomy shops. Here are two:

Eyepieces not fitting into 90-degree penta mirror


Here's the link to the user manual if you need it; http://www.bushnell.com/customer_service/manuals/telescopes/78-9440_Voyager.pdf Check the bottom of page 3, I think it answers your question - eyepieces should insert directly into the penta mirror. check page 9 for a diagram showing the whole assembly. If it turns out you have the wrong eyepieces, you can contact bushnell's spares department on; http://www.bushnell.com/customer_service/partsinfo.cfm?section=General%20Use Hope this helps, please ask again if you need more info :)
