Question about Celestron Advanced C10-NGT (600 x 254mm) Telescope

C10-NGT RA+DEC clamps and the motors

Hey, I have a question for you guys. I have a feeling it's going to be obvious. When using the motors in the C10-NGT reflector telescope model, do the RA and DEC clamps have to be tightened for no manual movement in order to use the motors at maximum efficiency? Or do you leave the clamps absolutely loose, so there can be manual movement, and motor movement? The only thing I've been trying is leaving the clamps loose; I'm afraid that I'll wreck the motors if I tighten the clamps and the motors will be trying to move, while the clamps are tightened.
So, leave the clamps tight or loose while using the motors?

Re: C10-NGT RA+DEC clamps and the motors

Holy man.. response is kinda slow. Good thing I tried it myself.

Sure as heck, you can leave the Right Ascension and Declination clamps tight while using the motors!
It makes a lot of sense, and many things much easier....
Thanks for the.. reply? lol. Just joking.

I can't find any documentation on how to remove the primary mirror for cleaning. I'm a newb and don't want to mess anything up. Thanks, Bob

First -- how do you know the mirror needs cleaning? Did you shine a flaslight down the tube and see some dust? Never use a flashlight to determine if a mirror is dirty-- they are ALL dirty when you use a flashlight to check them.

Only clean the mirror if it is interferring with the views through the scope.

There is a ring around the back-- remove those screws and the mirror should come out-- don't driop it! Then remove the mirror from the mirror cell.

I'm trying to use a T mount with a Canon DSLR. For some reason I can't get it to focus. Any help?

Sometimes certain cameras will NOT come to focus, especially in short tube reflector style telescopes. There is not enough back-focus to achieve focus.

Your website no longer contains the manual for the Telestar 114AZ model and I'm in desperate need of it's use.

This is a small reflector style telescope. Any of the REFLECTOR manuals has enough information to assemble and use this telescope. Look under the REFLECTOR heading for one that is similar to your scope.

Cant see any thing

Did you remove the lens cap? If the scope is like the picture in your question this is a REFLECTOR style telescope. It has a mirror in the bottom and a smaller secondary mirror under the focuser. The FOCUSER end is pointed UP. as in the picture above.

Can you focus on a distant object during the day time? Use the eyepiece with the largest number written on it and DO NOT USE the 2x barlow if you have one. Try focusing during the day time. If this works your telescope is OK. Then try the moon at night as your first target.

If you can see the moon up close all is OK.

I picked up a used Meade 114 EQ AS on the off

First go to Meade's manual web site -- look under the REFLECTOR heading and download a manual. Here:

Second-- It's NOT ASTROLOGY! It's Astronomy!

Astrology is completely fake and superstitious belief that the planets and stars affect your life!

The MIRROR is on the bottom of the telescope- this is called a REFLECTOR style telescope. The focuser is on the TOP (side) of the telescope. Make sure the focuser end is UP and the mirror is on the bottom pointed toward the GROUND.

Hello. I have a telescope, model 90076, but I cannot find the manual anywhere. Would it be possible to download one? Thank you :) Raquel

Your question does not include the BRAND of telescope; the number does not tell us what link of telescope you own.

However they all go together in the same way. There are two basic types of telescopes REFRACTOR and REFLECTOR. The reflector has a mirror in the bottom of the tube the refractor has a lens in front.

Meade maintains a list of manuals for all of their telescopes. Look under either REFRACTOR or REFLECTOR for one that is similar to your telescope.

The back of the manuals usually have suggestions on how to use the telescope.

Having just bought a used model I wish to know how

You will not find a manual for that specific telescope. However Meade maintains their manuals at this web site.

Look under REFLECTOR for one that is similar to your telescope. They all go together in a similar fashion.

Also you should read the beginner's telescope article on our Astronomy club web site, located here:

To the second guy posting the same problem-- you went and bought a cheap department store telescope--- what do you expect for $89-- ???

If you would have spent just a little bit more you could have had one of these--

Don't buy telescopes at Wal Mart or Sears!

4.5 inch reflector telescope --can't see anything

you have to make sure your primary mirrow is level, there are a set of screws that will help you do it, then the secondary mirrow at 45 degree, start in a daylight to align the telescope. good luck
