I need help!

To start I need to say, I feel that I have been ripped off by K-mart. In this link I could have paid so-so-so much less,but this is not my only problem. Ok.. some one needs to tell me how to work this wounderful object, the telescope a Tasco 40076420H. There should be a How To Guide. Thank You for your time. Jeniffer & Mychael Smith 03/13/2007

I just purchased a used Meade LX200 10" scope by mail. When I opened the box I found that the battery compartments AND the sheathing on the inside of both arms are missing. Have I been ripped off?

I assume you mean by sheathing the cabling to the RA and DEC motors and by battery compartment the control panel. If the seller stated that the scope was working, indeed you got ripped off. If by ratings you mean ebay I would contact them about a return and refund. If you got a great price, all is not lost since there is an upgrade to an autostar which will get you back in working order (but you need the RA and DEC motors). Autostar upgrade is about $ 520 but you will still need a 12V power supply. George Dudash 760 383 2741 sells these kits and can probably get the other parts you need to get going. I'm guessing this may cost around $ 800 total from what you say. If you paid more than $ 1000 for that scope I'm afraid you were ripped.

I have found a company that makes the "Science Tech 525" telescope.

Hope this helps.
Here is a link to an item being listed on ebay called a equatorial mount. That is the term for a precision telescope mount. This may be much more that what you need, but the price is tempting.
Take a look.
I understand how your nephew feels,
Hope this helps,

I just purchased a Polaris DS-60 by Meade and need a power supply and a operator & parts manual. Can you help me.

You can contact Meade for parts here:

Here is the manual:

It's a 12 volt power system, get the correct cigarette lighter style power plug from Meade -- it is center positive-- and use a 12 volt power pack like this one, or a car starter battery pack from Wal Mart. Make sure it has a cigarette style female plug.

Call Meade first and discuss this with them.

Bushnell Telescope 78-4678

A telescope like that has a very narrow depth-of-field, so you need to focus very, very slowly to be able to see any image. Try focusing on something bigger (like a spot on the moon) and adjust the crosshair accordingly. The two eyepieces gives different magnification.

I have a bushnell 450 tepescope and I need a new eye piece

Many online retailers sell eyepieces here are two:

Eyepieces come in 3 sizes. .965, 1.25 and 2 inch.

Measure the hole to determine the size, usually 1.25 inch, however many low cost toy telescopes use .965 inch. Just another reason to avoid buying scopes from Wal Mart, CostCo, Ebay, or Craigslist unless you know exactly what you are buying.

I purchased a used etx90ec. Two of the battery terminals are moderately corroded. The lights on the control do not come on and it doesn't work.

If you can clean up the battery terminals with sandpaper, then you will need to try an outside power source.

Buy either the 110 volt adapter or BETTER but a 12 volt power pack at Wal Mart (the kind you use to start a car) make sure it has a 12 volt cigarette lighter style plug.

You can buy either the 12 volt power cable or tthe 110 volt adapter from I never use the internal batteries, always a 12 volt power pack. The ETX likes steady 12 volt current.

If it does not work with the outside power source then something is burned out on the main board. You will need to return it to Meade for repairs. Here are several links you need. the 12 volt cable
