I was given a Tasco Luminova a couple of months ago that had no eye piece in it, i have since purchased one for it thinking that this was the only thing that i needed for it to work correctly. Unfortu


Tasco telescopes are not worth owning. They will only frustrate you and you will dislike astronomy. Buy a Meade, Celestron or Orion Even the Celestron 70 travel scope, although it has a poor tripod, will give you a great view of the moon and ok view of Jupiter and Saturn They are under $80

Have been given a, "used" Edu Science 525x reflector telescope (set) in case. I,m looking for the following help .... 1) needs to be inspected,and overall cleaning done', and adjustments made to be sure it is all there, and working properly. .. 2) Also need to get, a user guide, and instruction book for it, if possible, so can operate it properly, that shows the different lens, and their operations, and how to assemble ,where they go. Can you help me find this information, or locate a place that i can contact to handle these things . THANK YOU


This is sold by Toys R US. You will not find a manual. It will NOT achieve 525x that is a complete lie. Maybe 100-150 power. Meade has manuals for all of their telescopes. Look under the REFLECTOR topic for one that is similar to your telescope. They all assemble the same way.Then read my TIPS on my profile page.Here is Meade's manual web site:http://www.meade.com/manuals/index.htmlFoe information on cleaning optics read this:http://www.televue.com/engine/page.asp?ID=143

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
