First the picture in your post by FIXYA-- shows a reflector style telescope that is mount BACKWARDS! Notice that the eyepiece -focuser is on the DOWN end of the tube. The scope is pointing at the ground!

So if your scope looks like the picture -- turn it around and put the focuser on the UP end of the tube. Then take the scope outside during the day time. Put the eyepiece with the LARGEST number written on it into the focuser. DO NOT USE the 2x barlow if you have one. Practice focusing on a distant object during the day time; and read my tips on my profile page. DO NOT POINT the scope at the sun!! It will instantly blind you-- just point it at an object a good distance away and practice focusing.

Also read this page so you understand the different types of telescopes.

Purchase a 263/525 Reflector Telescope put it together, took off the eyepiece lens caps, but still unable to see anything. Does the end filter of telescope need to be removed?


The picture in your post is NOT a reflector style telescope:

This is a reflector:

Notice that the eyepiece is in the FRONT side of the scope. Take the front lens cap off-- the primary mirror is on the BOTTOM of the tube.

Can't see anything through the telescope


Have you tried looking at a distant object during the day time? Did you remove the lens cap? Did you put the eyepiece with the largest number written on it into the focuser and practice focusing on a distant object (during the day time)?

Read my tips on my profile page.

After i remove all the appropiate lens caps and align the red dot, i cant see anything out my lens except darkness. Total black background,day and night. Should i try something else,thanks.


Put the eyepiece with the largest number written on it into the focuser, do not use the 2x barlow. TRY AGAIN-- during the day time and practice focusing on a distant object.

The end with the FOCUSER is the UP end of the tube-- the mirror is on the bottom of the tube. Many beginners mount these BACKWARDS.

I cannot focus anything. Everything I see is completely black. No matter what do I can not get this contraption to work


This is a very simple refractor telescope. Put the eyepiece with the largest number written on it into the diagonal, then put the diagonal into the telescope. REMOVE the lens cap at the front.

Now practice focusing during the day time on a distant object.

Veiwing is like looking at a do-nut? nothing in center


The focuser and eyepiece are POINTED UP toward the sky -- the mirror is at the bottom of the tube.

Put the eyepiece with the largest number written on it into the focuser, and during the day time, practice focusing on a distant object.

Can't see anything through the lens?


You did take the lens cap off? During the day go outside and practice focusing on a distant object-- use the eyepiece with the LARGEST number written on it.

Can't focus on anything at all


Here is the manual-- read it cover to cover--
http://www.meade.com/manuals/TelescopeManuals/ETXtelescopes/ETX-90%20w-autostar%20man.pdf

1. Take off the lens cap

2. Put your lowest magnification eyepiece into the telescope on the TOP eyepiece port-- there is a lever on the side which rotates the diagonal mirror between the top and rear ports --- can you see light through the telescope? If not turn the lever.

3. During the day practice focusing on a distant object at least 100 yards away-- the image will be upside down -- this is not a problem-- no UP or Down in space.!

4. The lowest magnification eyepiece is the one with the LARGEST number on it.

D100 problem


It sounds like the mirror is locked up. Have you removed the lens to check?
