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 with this eyepiece during the day time on a distant object like a telephone pole or a building.

My son completely disassembeled all the parts and lenses of his microscope. how can i find out how to correctly put it all back together?


The image is of a telescope. This type of scope has only one optical part in the tube, a mirror on the end opposite the focuser end. The smaller tube just goes in to the focuser and it uses a small screw to hold it in place. If the lenses are truly taken apart then there may still be hope as most critical optics are glued together with crystal clear glue.Clean them and reassemble.

My barlow lense is making it hard to focus


Only answer is depends on your optics. Maximum practical magnification is 50x per inch of aperture on very good conditions.
If you have a store brand telescope, the optics are poor (both the scope and the optics) it can't handle the magnification.
High magnification requires a good , clear night.
Allow your scope to reach thermal equilibrium before viewing.

How do i set up eye pieces and focus lenses?? Instruction manual came in chinese with no translation and we are begiiners!


During the day:
1. Point to a far (1000 meters or more) object
2. Insert the lowest power (highest number) eyepiece e.g. 25mm
3. focus on the object.
4. Align finder to match what you see in the scope.
At night.
1. Put scope out and let it reach the temperature of the outside.
2. Point finder to the moon (1st object you should always use to check scope and finder alignment)
3. Use the same low power eyepiece.
4. If everything seems fine, switch to a higher power eyepiece and enjoy the view. You may have to slightly adjust the finder to align with the main scope.
If the views are blurry, the telescope may be out of collimation. Look on the internet for generic collimation instructions.
If this still did not help. Throw the scope out! Its probably a piece of junk and will only discourage you.

We have our telescope set up but cannot see anything out of the lenses. we have tried all different lenses but without success. Currently there is one star we can see with our naked eye. We cannot see it...


If you look at the PICTURE in your qusetion FIXYA has the scope POINTED at the ground! :)

You have a reflector style telescope. The mirror is the bottom of the scope, and the focuser is on the UP end of the tube pointed UP. Many beginners mount these scopes UPSIDE DOWN with the focuser on the bottom instead of the top (side) of the tube.

Put the eyepiece with the largest number written on it into the focuser. DO NOT use the 2x barlow if you have one. Take the scope outside during the day time and practice focusing on a distant object. You must also line-up the small finder scope on top with the main tube.

POINT the scope at the top of a distant telephone pole. Without moving the main tube, adjust the cross-hairs on the finder scope so they point at the same spot as the main tube.

You do not have enough BACK-FOCUS, you need an extension tube for the focuser like this one:

I have a Vivitar Telescope 60x/120x VIV-50600. Once I locate the object with the scope finder and I try to view it through the bigger lens nothing is focused. I have tried using the adjuster and nothing...


The only thing I can think to ask is whether you have fitted an eyepiece (NOT the barlow lens, if it came with one). Eyepieces are small lenses marked with a focal length (in mm, like 20mm or 9mm). They fit into the part that does the focussing, and are held by a small screw that you tighten with your fingers. If you have fitted an eyepiece and it still won't focus then I don't understand what is going on.

I would suggest that this is one of those problems best sorted by an experienced person physically present.

Put the eyepiece with the largest number written on it into the focuser. DO NOT use the 2x barlow if you have one.

Go outside during the day time and practice focusing on a distant object using the eyepiece mentioned above.

Line up the small finder scope with the main tube-- point the scope at the top of a distant telephone pole or church steeple.

Without moving the scope, line up the cross-hairs in the finder scope with the same object. Once this is lined up you can use the small finder scope to locate objects in the sky.

My scope will not focus it seems like the focal length was somehow knocked out


Yes it will focus. Put the eyepiece with the largest number written on it into the telescope. DO NOT use the 2x barlow. Go outside during the daytime and practice focusing on a distant object.

PS- focal length refers to the distance between the front lens of the telescope and the eyepiece. Are you saying the focuser itself BROKE? If it is missing the scope is not worth fixing, as a new focuser will cost you about as much as what you paid for the scope.
