20 Most Recent Celestron NexStar 114GT (269 x 114mm) Telescope Questions & Answers

Astro telescopes normally do show an inverted image, since for most purposes this does not matter. For terrestrial viewing, such as thru someone's window, you can buy an "erect image" or "correct image" prism which gives an upright image. http://www.optcorp.com/telescope-accessories/optical-tube-accessories/diagonal-prism-eyepiece-holder.html?a_diagonal_design_f=1090 I don't know of such a thing for the finder scope, you would have to buy a new finder. http://www.optcorp.com/celestron-9x50-illum-ra-correct-image-finderscope-93781.html

Eyepieces come in two popular sizes 1.25 in. and 2". Some older 'scopes have 0.96 inch eyepieces.

Does the focuser move in and out when you turn the knob? If it does then go outside during the day timne and practice focusing on a distant object. Use the eyepiece with the biggest number written on it.

This will give you the lowest magnification-- which is easier to focus.

You need to buy a USB-to Serial adapter cable like this one:

scopestuff.com sells these. The Keyspan brand USB-Serial adapter is also a good one.

Usually the lens cap just pops off -- the bottom where the mirror is located should not be removed.

These scopes do NOT have screw on lens caps. ?

And what is your question?

Only Celestron will have that part. Contact them here:

Can you see something in the distance during the daytime?

Did you do the training, set the TIME
Did you do a two star alignment?

You must follow the setup procedure exactly for the scope to have accurate gotos.

Get the manual out and read it several times. You can practice inside just to get familiar with how the scope operates.

You are NOT in focus. Turn the focus knob a little until you see a perfect "disk" for the planet. Stars are always POINTS of light, with a telescope or without a telescope.

This scope does NOT need to be polar aligned --

Here is the manual:

This is an ALT AZ goto scope. Read the manual above. You use the hand controller to move the scope in Altitude and Azimuth(left-right).

You must align it on 2 stars in order for it to has successful gotos.

Read the manual above.

Yes, that's the point of it.

Remove the entire (full diameter) cap for stellar and planetary viewing, or just the smaller diameter central cap for viewing the Moon which is far brighter and is too bright without either adding a neutral density filter or by partially masking the optical tube assembly.

Hi Dan, before you ship it off somewhere, you may want to try and change out the hand controller with another one that someone has and see if the problem moves.

I don't know what a Celestron would take, but as a point of refrence, the Meade telescopes typically take 1 hour.

Call any Celestron dealer.
