Can't see anything through the lens. We sight


Put the eyepiece with the largest number written on it into the telescope. DO NOT use the 2x barlow if you have one. Practice focusing on a distant object during the daytime and read my TIPS on my profile page.

I also have a jason mercury 420 telescope and was wondering if you knew where i could find a users manual bc I am having problems with my small lenses. I can see objects with just the telescope lens but when i put the small lens into the telescope tub the object bc so distorted or even total blackness...... I have played with the adjusters and still dont understand why I cant see anything. Please help. Thanks Ashley


You are using too much magnification. Put the eyepiece with the largest number written on it into the telescope. DO NOT use the 2x barlow if you have one. Take it outside during the day time and practice focusing on a distant object.

How to use the 40-114675 telescope,ive got it set up but carnt see anything. It came with a black circular card in the lens which i have taken out.How do i see anything? is card ment to be in or out thanks Steve


Light enters the front of the tube -- TAKE the lens cap off-- goes down to the bottom of the scope and its the primary mirror--- then bounces back up and hits the tiled secondary mirror which sends it OUT to the side into the focuser and the eyepiece. The largest the number on the eyepiece the LOWER the magnification. Start with your lowest magnification until you learn how you focus. Try this during the day time on a distant building or telephone pole.

Just black Hi I just recently bought a Meade ds-2114ats-tc and I tried to use it last night with the kids, unfortunaltey after we set up the telescope all we could see was black. Yes we did make sure that the lens cap was off and that there was nothing blocking anything, we also tried setting it up in a couple of different spots in the back yard where we were close to a light source and also away from a light source. Basically everything I tried did not work but I am new to this so I could be doing something wrong still. I tried to manually look at the brightest star in the sky and still nothing....just black. Could I be setting this up in an area where there in either not enough light getting in or to much? This is my first time using a telescope so I don't even really know if I should be setting this up in the complete dark area or with a light source around like a backyard light for example. I am extremely confused please help.


I just got one of these today and they are different. My guess is you are having a focusing problem rather than alignment. Assuming of course you are removing the larger dustcap and not just the smaller one ha ha ha. The instructions include how to align but maybe you can use this Mine has two dustcaps, one full size with a smaller one in its center. Had the smaller one been offset it could have been used as an aperture stop to reduce thermal effects on bright objects such as Jupiter and the Moon. Another thing is a built in barlow within the focuser draw tube. This inreases the focal ratio of "f" number and makes align far more trickier than if it had been a straight Newtonian. Set-up the scope under and point at the bright blue sky in the day time. Pull off the small center dust cover and make sure the diagonal holder is centered under the small hole in the larger dust cover. If not that can be accomplished by adjusting the three thumb nuts on the front edge of the tube. Once this is done remove the larger dust cover and peer into the focuser from the side with the eyepiece removed. You should see blue sky and all the components should be centered. One can judge fairly well that their eye is centered but a simple trick is to draw an eyepiece sized circle on a piece of paper and using a pick or pencil, poke a small hole dead center on the circle. Place the circle centered over the draw tube and peer through that. No other tool will improve on the accuracy of this almost free and simple one. Now moving your eye closer to the focuser you should see the reflection of your own eye or in this case the hole in the center of the paper. The paper reflects and transmits enough light that it provides a bright enough targert to canter. Now you must experiment to determine which component is mis-alighned and what adjustment is required to correct. Try flexing each componet before loosening any adjustment screws.This will give you an idea of which component and in which manner it needs to move. Now my guess is, while you have some mis-alignment the almost f:9 focal ratio makes the image extra dark and so contrasty that if you are out of focus all you will see is dark. With your 28mm eyepiece, now point the scope at a daylight scene some distance away and bring the image to a focus. Note hoe far your draw tube is extended so you will be in that neighbohood come night time. I suspect this was your problem more than mis-alignment.

I have lost the assembly instructions for my grandson's beginner telescope. I have it assemled properly, I beleive, but the set screw that holds the lens in place does not seem to penetrate the housing far enough to hold the lens secure. What should I do? I don't know what model it is, it has no identifying numbers but it is all black plastic with aand a little imitation silver metallic plastic on the bottom. The only lens supplied is a 20mm lens. Will we be able to see anything?


Hate to tell you, but we receive more complaints about this brand of telescope than any other! Is this a REFRACTOR with a lens in the front, or a REFLECTOR with a mirror?Any well stocked hardware store can supply you with the small thumbscrew that hold on the eyepiece. BUT this scope is being sold by TOYS R US! What does that tell you about it!Next time buy your grandson THIS telescope:http://www.telescope.com/control/product/~category_id=classicdobs/~pcategory=dobsonians/~product_id=08942

Why can't I see anything? I have removed the lens cover (the whole thing). When I take the eye piece out adn look through the focusing mechanism I can see light and very small images. When I put the eye piece in I can't see anything (all black). What am I doing wrong?


Put the eyepiece with the largest number written on it into the scope and try again. Contact Bushnell directly for repairs:http://www.opticsplanet.net/bushnell-warranty.html

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 received a rokinon diamond black 1000x114 telescope. when i assembled the scope i could not see anything in the viewer lens on ther side. i noticed that the large mirror had a black cover it.


Newtonian telescopes (as the one that you got), needs to be calibrated, not just assembled. It is quite difficult to calibrate it and it may look almost impossible if you have no experience at all about this kind of telescopes.As the calibration procedure is quite long to explain, I will provide you the link to a website that details the process. You MUST read, understand and try again and again until success.Good luck!Link: http://www.skyandtelescope.com/howto/diy/3306876.htmlBy the way, be sure to remove the protective film from the lens. Read the user manual received with the equipment.

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.
