No, you burned out the power circuit board inside the scope base. Only Celestron can repair this, contact them here:

I have a 1998 buick park avenue ultra and my sound system was grounded and it shut my car off when I tried to restart it it went into security mode and will not start now I do not see the gear indication...


if you really feel the radio caused the problem try disconnecting it. then try to start it. is your car cranking when you turn the key ? Many times you may blow a fuse that controls electronics on your motor. like fuel pump, computer modules etc. Fuzz makes safety fuses that light up when they blow out. yeah its a pain to switch all the fuses but when one goes, having to look threw a few dozen to find out what one went as opposed to looking at the one lit up telling you it blew is much faster and easier . especially on those cold rainy nights when your lights blow a fuse and your trying to find out which is your light fuse.

I have the Nexstar 8. It will not auto align or manual....


You must set TIME, DATE, and SITE-- probably does not know your actual location. Read the manual and perform all of the setup procedures.

Some of these have a "starting position" again read the manual and make sure you are in the "home" position before you start the alignment. Read my TIP on my profile page about GOTO telescopes, and join the NEXSTAR forum on www.cloudynights.com

Sirs: I'm the party with the "Rate Control" issue I have a new NexStar 8se.


The Rate Control only works for moving the telescope using the arrow keys. It does NOT work while doing an alignment, and GOTOs always slew at the max rate of 9.

For any other issues I would suggest you first RESET the hand controller and see if this corrects the problem and if NOT then reload the latest hand controller and or motor controller firmware, using the Celestron update cable and a computer.

I have a celestron nexstar 5 the begins to move on it own


Many times a bad cable will cause this. Also low batteries can cause this.

Contact Celestron and order a new cable. Use an external 12 volt power pack.

2-star alignment


I also have an 8i, but decided not to upgrade the controls yet. I've had my scope for about four years. I have experienced the same problem and am not sure what what causes it. Some nights, the scope tracks alignment all night, other times it does not. When the later occurs, the only thing that helps is to repeat the alignment picking new targets. One night, I had to repeat alignment 3-4 times. Also, I highly recommend a book by Michael Swanson, "The Nexstar User's Guide". It's an easy read, very specific and keeps the novice in mind. It should be included with every Nexstar sold. Go online to: http://www.Nexstarsite.com. Hope this helps. John

Be sure that the Azimuth Axis is Lock, you migth want to try and move the telescope in the Azimuth to make sure it is it is locked. Be carful not to force it. I have seen on some post where the locking part of the Azimuth somtimes breaks. and the Azimuth Axis will just spin freely Locked down or not.

GoTo Problem


Be sure that the telescope is configured for EQ SOUTH mode to tell it is in the southern hemisphere. Once a star alignment is completed NEVER manually move the telescope. Use only the control panel to slew. Everytime the telescope is move by hand, the motors do not know it has been done, and assume it is still pointing at the old direction. Check the manual for setup.

A low voltage power supply is the usual cause. You must use fresh batteries and or a seperate 12 volt power pack.

Also you must accurately;y do all the setup-- like Time, Date, and Site properly. Read the setup in the manual again.
