How to look at stars

Your telescope is fortunately of a type (a refractor) that is ready to go once you take the lens cap off, and mount an eyepiece in it.
The magnification you will get does not matter much if you are looking at stars, but it is the focal length of the scope, 900mm, divided by the focal length of the eyepiece. So for example 900/20 = 45x.
The next step is to obtain a sky chart such as

(adjust this to show the local horizon) and then either print or take the PC outside and match it with the constellations you see.

Some stars are more interesting to look at because they are coloured (Betelgeuse - Alpha Orionis) or actually double stars (Rigel Kent - Alpha Centauri). See

Another way is to identify a Constellation, and then look up Wikipedia for that. You will find info on the resident stars there eg

I need a manual for the jason constellation 280. Do you know where I could find one?

You will not find a manual; for this small telescope. That is the problem with buying an off brand telescope.

Also even if you had a manual, it will not tell you how to use the telescope. It only has assembly instructions.

Can see any thing vivitar Please Help frustrated and confused

Put the eyepiece with the largest number written on it into the "diagonal" that came with the telescope. DO NOT use the 2x barlow if you have one.

Go outside during the day time and practice focusing on a distant object. The moon should be your first night time target.

Can not seem to focus when we look through the lens we just see the bk=lack sky we cannot seem to see anything

try this:
see the mini scope on top of the telescope?--that's called the finder scope--
you look through that to see what the telescope is aimed at, just like what a sniper does before he pulls the trigger.

put in the lowest power eyepiece you have in the telescope, the one with a high number on it.

it's a good idea to align the 'finder' with the telescope during the day time--it's much easier.

if your telescope and finder scope aren't aligned properly, aiming your telescope at any target will be off and you'll just get frustrated.
to do this, look through your finder scope and pick a far away target, put in the lowest power eyepiece you have, that's the one with a high number--
high number = low power = a nice big view in the telescope.
low number on eyepiece = high magnification, like a zoom lens.

always use the lowest eyepiece first, then work your way to higher magnification, if you want to get a closer look at your target.

use lowest power eyepiece in telescope--> look through finder scope -->focus the image--> switch to higher power of eyepiece for a closer look at your target.

practice this during the day until you're comfortable, then try it at night.
try the moon, it's a nice big target

you can also use binoculars to check out the night sky.
you can try using 7x35 or 7x50 binoculars.
you see a lot more stars and it gives nice big views of the stars and constellations...and the moon...

hope this helps :D

How to use telescope at night?

Many people have the same problem-- with these small telescopes you are stuck with seeing only the moon, and several other planets, and maybe a few bright star clusters.

These are all TINY objects (except for the moon).... when you look through the telescope you are looking at a section of sky about the size of your fingertip held at arms length-- the scope must be pointed DIRECTLY at the object. Practice on the moon first-- and then try to find Saturn which is up in the sky right now-- it looks like a dim (slightly yellow) star.

Cant see anything

Well you -- like hundreds of other people-- bought a department store telescope. Put the lowest power eyepiece in the telescope-- it's the one with the LARGEST number written on it.

Practice focusing during the day time on a distant object. I know the box said 500 power BUT you will only get about 100 power or less maximum that you can actually use.

I have bought a Vivitar Reflector telescope and could not find instruction. Where I can find it to resolve a problem?

If it is like the picture you posted it is a refractor style telescope on an Alt Az mount. Very simple to use -- left and right--- up and down.

However you also need a star chart to find things in the sky-- download one for free at:

Also try to find a local Astronomy club and attend some of their meetings and star parties. Your first sky object should be the moon -- the next time it is up at night.

Jupiter and Venus are also up right now.... check the star chart above.

GoTo Problem

Be sure that the telescope is configured for EQ SOUTH mode to tell it is in the southern hemisphere. Once a star alignment is completed NEVER manually move the telescope. Use only the control panel to slew. Everytime the telescope is move by hand, the motors do not know it has been done, and assume it is still pointing at the old direction. Check the manual for setup.
