Celestron nexstar 11" gps scope

Bought this scope in May of 2002, has always worked like a charm, last night I set it up for the first time this year. it wasn't quite dark yet but turned it on and pressed gps align and it started leveling itself and slewing towards north. once it got to north it emediately started slewing for the first alignment star [Cappella] couldn't see the star yet to align in the telrad before centering in eyepiece so I was satisfied and turned it off to wait until dark. when it got dark I proceeded turning it on, pressing on gps alignment it before it gets to north it stops in its track. I tried sever

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.

Celestron nexstar 8 i series alignment trouble

Kind of late with my answer...BUT if you pop off your GPS unit and then just tilt it up and down CAN YOU HEAR a ball bearing moving inside...??? YOU SHOULD....that is how the GPS actually finds the level position of the OTA....sounds like it is stuck..OR even worst that you have a CN-16 unit that was designed for a GEM mount which is not designed at all for leveling the OTA...Next thing.. exactly what version is your hand controller...version 2.3 ????

I have a CPC11GPS telescope that was working the last time I used it, which was 6 months ago. It is in NEW NEW condition. I pulled it out last night, turned it on, allowed the system to align itself using the GPS system aboard. I then tried to center the first star using the RA and DEC directional buttons. The Dec buttons moved the telescope up and down, but the telescope would not move in RA. I also connected the scope to my SKY program, it also moved the scope in Dec, but not in RA. What could have happened since it was last used? The only previous problem I encountered was alignment and intermittent RA movement, I sent the scope to Celestron, who worked on it and returned it. Those problems were never corrected by Celestron, a year ago.

The clutch is not engaging in RA. Maybe the gears are not actually meshing together? A loose worm gear?You can open it up and look and see if anything obvious is loose. Otherwise it's a trip back to Celestron.

Celestron Nexstar 114gt telescope,hand controller lights up only

Do you have a fresh set of batteries in the scope? Better to use an outside 12 volt power pack with the Celestron 12 volt "cigarette" lighter cable.This can be three things:Low powerBad cable from hand controller to scope.Or a broken hand controllerTry fresh batteries first.

Focusing Issue Last night, I used my Celestron 11" NexStar11GPS for observing and astrophotography, and it worked like a charm. Tonight, with the same equipment, I am unable to focus the telescope at all. I turned both the coarse and fine focus knobs counterclockwise as far as they will go, but every object is still out of focus--and once I reach a certain point in turning the focus knobs, the object simply moves in the eyepiece rather than becoming more focused. This problem is present with or without the use of a diagonal. The only thing I did with the telescope between last night and tonight was to mount a Celestron StarPointer (a holographic sight-type finderscope) onto the side of the telescope tube's back end with some 8x32 3/8" screws using pre-drilled screw holes. What happened?

The screws should be short enough not to stop the primary's travel, but pull them out and try it again. Good luck! George.

Aligning my scope and slewing problems

You need to synchronize the telescope with stellarium. Center the telescope on a known star, then select the same star on the laptiop and 'synch' with it.

Telescope I've just got a Celestron Nexstar 102 SLT. Complete novice. I am finding that after alignment the scope slews either vertically up or down before I have selected any target. I have to switch it off before the scope hits the mount. Any ideas ??

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

Hi, Could you please tell me where I might be able to get my Celestron Nexstar 11 GPS Telescope repaired? The corrector plate needs to be replaced. Is there anyone that could help with this? Regards, Geoff.

The scope will need to be returned to Celestron. The Corrector plate must be matched to the rest of the optics inside the tube. This is an EXPENSIVE repair ! Call Celestron here:
