    Really need to know more to give an answer. Is it a reflector or a refractor? Have you removed the dew cap?

Put the eyepiece with the largest number written on it into the focuser. DO NOT use the 2x barlow. Practice focusing on a distant object during the day time.

Is it possible that something inside a telescope could get jarred out of place or alignment and that is the reason I can't see much thru it ?


If it's a reflector, then you have two mirrors that could get out of alignment, but you probably will still be able to see something unless it's way out of alignment- usually the view will just be blurry or misshapen. Less likely the problem with a refractor unless you dropped it or gave it a serious whack. When you're first trying to find an object, use the LOWEST power eyepiece first, because that gives you the widest field of view and you're more likely to see the object even if your finderscope is a little out of alignment.

When you line up the finderscope, make sure you center a large object in the main telescope FIRST, using the lowest power eyepiece you have (the lower power eyepiece is usually the longer one), then adjust the finderscope so that its crosshairs are right on the object while it is still centered in the main telescope. Use the Moon, or during the day, a roof peak or top of a telephone pole. If you reverse the process, you won't be in alignment. There are lots of other reasons you may not be able to see something, but lining up the finderscope is something you should do at the beginning of every observing session. Try it first during the day so you can see what you're doing.

Hi ive got a galaxsee tasco telescope but im having trouble seeing anything at night, i've took all the caps off lined up on a star but its just pitch black can you help thanks.


1. During the day, point the scope towards an object and align the finder scope to the telescope.
2. First object at night should be the moon. it will verify your finderscope alignment and you should have a clear view of the moon.
3. Use your lowest power eyepiece (largest number in mm) and point the finderscope to a star. The star should be in the center of the eyepiece.. If not, adjust the finder until it and the scope are centered.
4. You can use your higher power lens on the star nd it should still be in the FOV (field of view)
5. Scope may need to be aligned (collimated). Instructions on this should be included with the scope

I can't see anything out of the large scope


Use the 20mm to view an object (building, tree etc.) far away during the daytime. Align the finderscope to the object.
To view the moon, leave the scope out to equalize the temperature for at least 1/2 hour. Use the 20mm and no barlow. Point the scope towards the moon by sighting along the barrel of the scope, then use the finder to zero in on the moon. You may then switch to the 4mm eyepiece. for a more magnified view of the moon. You will have to keep moving the telescope because of the earth's rotation. The higher the magnification, the more you will have to adjust the scope. Because of the cheap finderscope, finding the planets will be difficult. Best to always sight down the length of the scope to get you close. The planets will be small and indistinct.
This is not a astronomical telescope! May be used for views of the moon but the cheap mount is not suitable for other planets. Max power would be 225x NOT 420x as advertised. The erecting prism is for terrestrial use only.
Nothing discourages an amateur astronomer more than a toy store telescope. My advise would be to use this scope for nature watching and go buy a good telescope (Meade, Celestron, Orion etc.). Even Those 60mm refractors are superior to this! A descent scope would cost a minimum of $200

Just bought a Bushnell telescope 78-4501 - set it up as per the instructions. I can see objects light etc... through the object finder or view finder but I see nothing through the telescope not even...


This is not a real telescope, it is a toy. You will be lucky to see anything with the 20mm lens only. the rest are junk. The telescope needs to be collimated (see your manual) and the finder aligned with the telescope. Align the finder with the scope during the day, although this model was known for poor mounting on the finderscope and will become un-aligned easily.

Completed setup, can't see anything through eyepiece.


I answered your question already-- TURN THE SCOPE around you have it mounted backwards! The eyepiece end is pointed UP. Like the picture above in your question.

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.

Finderscope image upside down & not focused if viewing past 100 yards


The upside down image is normal for astronomical telescopes. The finder usually is a fixed focus, but it can be altered for various eye types, by rotating the objective lens for focus - the cell should move in or out on fine threads.

I really do not know how to use it. It's rather awkward to look through the lens. What does the red dot finderscope really do?


1. Please read menual proper.You can see live demo through company website also.
2. Start with lower resolution eyepiece.For thet you see the meximum number on eyepice.Than you start first to see moon.Because mon is a brightest obect of the sky 7 easy to find.than you go planet etc.
3.Finderscope is a taegt shooter.Please switch of finderscope.You can see two red dot in the finderscope. Than you aline the object ine sky with two red dot. Move the telescope up to in line(Obeject which you want to see and two red dot).
Now you can see in the eyepice to megnifing image of object.
