Eyepiece for telescope

Hello, I have a cheap Vivitar telescope. I was wondering if I could increase magnification from 100X to as much as possible by replacing 6mm eyepiece with another one for example 4 or 3 mm. OD of the scope's eyepiece is .965. I know that most eyepieces are 1.25OD. I can buy .965 to 1.25 converter, but I have a hard time finding innexpensive <4mm eyepeace. Could you help me locate such an eyepiece?
Thank you in advance,
Tony G.

However-- it is very doubtful if your scope can exceed 100 power without the image degrading. I normally use 100-150 power MAXIMUM in my 8" LX90 ---usually I use 50-100 power.

    Hate to break it to you but that little telescope will never reach 500x--- under perfect sky conditions and perfect OPTICS the rule is no more than 50 times aperture-- your aperture is about 3 inches-- or less-- so 150x is the maximum possible magnification under PERFECT sky and PERFECT scope conditions--

    Once you exceed the maximum optics the image just gets BIGGER and FUZZIER AND DIMMER! --

Vivitar 76mm reflector teles.76700 barlow lens 3x eyepiece is to small for it.is there a reducer for the barlow ?kit came with two 3x barlow.same size


No the barlow increases the magnification by 3 TIMES for any eyepiece --
this will be too much for that small 76mm telescope.

Magnification is the least important quality of a telescope. Aperture and quality ioptics are much more important. I usually never use a barlow -- just the straight eyepieces in various mm sizes.

Can not see out of scope...missing internal lens?


This is a toy not a telescope. If you want to waste money on this measure the diameter of the eyepiece holder. It is either 1.25 inch or .965 inch. Buy the appropriate sized eyepiece. There are many vendors on the web. The most useful magnification is 100x so the highest eyepiece will be 20mm

Missing eyepiece.


You can buy an eyepiece from 1000 different retailers-- just get the correct SIZE usually 1.25 inch BUT many of these smaller scopes have .965 eyepieces-- MEASURE the hole. Here are two places that sell eyepieces--

You don't need to get Vivitar brand eyepieces to get additional ones for your telescope. I'm not sure of the specifications for this particular telescope but in general they come in two barrel sizes for the eyepieces. The diameter of your eyepiece is probably 0.965" but could come in the more standard 1.25". You can measure the diameter and determine this quickly.

Once you know the diameter to shop for you can look for the focal length of the eyepiece you wish to purchase. They are rated such as 4mm, 10mm, 25mm, etc. The smaller numbers give you higher magnification. You can calculate the magnification by dividing the telescopes focal length by the eyepiece focal length. For example, let's say your telescope is has a focal length of 360mm and you have an eyepiece rated 10mm. Divide 360 by 10 and that gives you a magnification power of 36.

You can find eyepieces at many telescope dealers on the internet. Your selection will be far less if you use 0.965" eyepieces. You can purchase 0.965" to 1.25" adapters so that you can use the larger eyepieces with your telescope. However, on some telescopes the adapters will cause the new eyepiece to not come into focus.

You'll also find that eyepiece prices go all over the place. A good general purpose eyepiece is a type called the Plossl. The better eyepieces have more coatings too that allow more light to get through to your eye. You'll find these listed with terms like "fully multi-coated".

I hope this helps.

Good luck and clear skies!

Eypieces in telescopes usually come in two sizes .9" and 1.25" diameter. There are hundreds of scientific companies or telescope companies that can supply you with an inexpensive replacement. The eyepiece focal lengths, usually in millimeters, determines the magnification of the telescope. The focal length of the main lens divided by the focal length of the eyepiece is the magnification of the telescope. Usually two eyepieces are enough for your scope. Good luck

Lens size/ power


It is generally bad to go higher than 50 power per inch aperture, due to the wave nature of light. It will magnify, but the image will get steadily worse, and be 'fuzzy' and unable to sharpen. If the telescope is 60mm, then the maximum practical power is 118x
If you insist on going higher, consider the use of a barlow. That will make the eyepieces that you have go 2x greater magnification.

Replace Eyepiece on Saturn F-900 Model 60EQ


You need an eyepiece This scope uses .965in eyepieces. you can find them on Ebay. Maximum magnification is 100x NOT 420x. These scopes have inferior optics and terrible mounts. Don't spend much on this scope. Buy a 20mm (35x magnification) http://www.ebay.com/itm/Astro-Optics-20mm-965-Telescope-Eyepiece-NEW-/230688144635?pt=LH_DefaultDomain_0&hash=item35b615bcfb or a 15mm (45x magnification) http://www.ebay.com/itm/Astro-Optics-20mm-965-Telescope-Eyepiece-NEW-/230688144635?pt=LH_DefaultDomain_0&hash=item35b615bcfb on Ebay If you are interested in astronomy, you need to spend some money on a good scope.
