You never said if this is a refractor or a reflector (with mirrors). If it is a refractor you need to collimate the from lens cell-- this is fairly difficult without an optical bench.If you have a reflector with mirrors then watch this video to learn how to collimate a reflector style scope.Here:http://www.andysshotglass.com/Collimating.htmlwww.telescopeman.orgwww.telescopeman.infowww.telescopeman.us

I have just bought an Astrolon telescope 288 power. I've assembled it following the instructions and I can't see anything. Inside the house I can pick few images but they appear upside down rather than laterally inverted as the instructions warn. This would be a minor problem if my child could at least spot a star through his brand new telescope, but it has been impossible to see anything except a blurred shadow. I tried watching a flying plane which was near and clear enough, but to no avail. An absolutely frustrating experience for my son who trusts Santa's efficiency!!! If the telescope is correctly assembled, what else could be the trouble? Thank you, Marta


All astronomical telescopes show upside down images --- it's normal.Stars are always points of light no matter what telescope you own. Download this star chart:www.skymaps.comObjects in the sky are tiny, smaller than the tip of your finger held at arm's length, try for the moon FIRST which is large. Then try Jupiter which is that very bright "star" to the Southeast after dark.Read my tips on my profile page.

I can't see anything through the Main Telescopic Tube


Did you take the lens cap off?You have a small 60mm refractor style telescope. Put the eyepiece with the largest number written on it into the telescope. DO NOT USE the 2x barlow which you might have that doubles the magnification of the eyepiece. Your scope is too small to use the barlow. Remember most binoculars are 7x50mm. So your aperture is not much bigger than a pair of binoculars.Now go outside during the day time and practice focusing on a distant object using the eyepiece with the largest number written on it.This may also help you:http://www.texasastro.org/telescope.php

Telescope: can't see anything except shadows


Put the eyepiece with the LARGEST number written on it into the telescope and take it outside during the day time and practice focusing on a distant object. DO NOT use the 2x barlow if you have one.You never said what type of telescope? Is this a REFLECTOR with a mirror inside? or is it a REFRACTOR which has a lens mounted on the front.Read my Frequently asked questions TIP on my profile page.and also this web site:http://www.texasastro.org/telescope.php

I have a 21086 and cannot see anything?


Put in the eyepiece with the largest number written on it--- and take it outside during the day and practice focusing onj a distant object. The moon should be your first night time object.

I can not get the telescope to focus. The viewfinder will not focus in. and can't see anything out of the out of the optical tube.


This type of telescope is viewed from the small tube at the rear. Use the longest lens you have. Most people think that they need magnification, but that is not accurate. A 5 mm lens will only have 1/6th the field of view (how much sky you see) compared to a 30 mm. The picture below was taken through a 50 mm lens.

Image through telescope is tiny!


Never heard of that brand of telescope. Next time buy one from one of these retailers:http://www.agenaastro.com/Telescope-s/1.htmhttp://www.optcorp.com/http://www.telescope.com/control/main/Try putting the eyepiece with the largest number written on it into the telescope. Then go outside during the daytime and practice focusing on a distant object.

I own a Mossberg Model A "Spotshot" 20X target spotting scope which I bought back in 1953. It is in excellent condition except for the fact that all of the internal tubes and lenses were removed for cleaning some years ago and I lost the order in which they have to be re-assembled. The optical train consists of the following: 1. optical "stop" with 1/2 " hole, thickness 1 mm 2. aluminum tube spacer, length 41 mm 3. " " " " " length 19 mm 4. " " " " " length 18 mm 5. " " " " " length 5 mm 6. Lens, dia 12 mm, focal length 22 mm 7. Lens, dia 9 mm, focal length 16 mm 8. Lens, dia 3 mm, focal length 22 mm 9. compression coil spring 10. objective and eyepiece ( No question about where they go.) I measured the focal lengths using the sun as the source, and a mm scale. They are approximate. I thought I could use the above information to figure out the order of assembly, but so far without success. I'm down to trial and error, which is driving me nuts. I sure hope you can help. Thanks in advance for your help.


As I had rebuilt many zoom lenses in my lifetime the ground glass on the back side is what you are looking through on any scope. It magnafies that way to capture the entire image of the frame your focussing onto. Now the lens the nearest to the eye is producing the smallest image and graduate in a larger size each steped up.. Look at the below link to get an idea

I bought and assembled telescope but we are new to telescopes and cannot see anything. I put the lense in correctly. I pull out the bottom cap and can see myself in the mirror within the tube. On the other end there was a black fabric covering an silver metal piece and there is no way to see out of that so what am I doing wrong?


POINT THE END with the cap toward the sky. The mirror is on the bottom of the scope. Then put the eyepiece with the largest number written on it into the focuser, practice focusing on a distant object during the day time.
