Nexstar 4SE handset will not power on

New purchase. Have checked batteries are ok

Posted by on

  • Helen Doyle Jan 08, 2013

    I've read elsewhere the problem may be because I am using rechargeable batteries so I purchased a set of new alkaline batteries but these don't work either. I'm going to have to send it back but just want to make sure there's nothing else I need do other than press the on / off switch which is located just underneath the handset. This switch is next to a connector which looks a little like an aerial connector but the diagram on page 5 of the instruciton manual omits to label what it is and the arrow on the diagram pointing to the on/off switch isn't really pointing to the right place.

SOURCE: new batteries put in....It doesn't power up

Are you SURE you installed the batteries correctly? I once installed them with ONE battery reversed. !

Jiggle the cable to the hand controller, you might just have a bad cable. You can buy a new one from Celestron.

If you can get a 12 volt power pack and the proper power cable or the 110 volt power pack-- try it on direct power. If this is a new scope I would return it to the deal if these simple fixes do not work.

SOURCE: New out of the box,

RESET the hand controller-- then turn it off-- wait 15 seconds and turn it back on. If this does not fix it the firmware will need to be reloaded. You will need a special cable from Celestron to update the firmware.

I would simply return the scope and get another one-- if the scope is new.

New out of the box, our Celestron Nexstar 4se does not ask for our location. Cannot find it anywhere in the controls to input, therefore it will not align.

I just received New Star 4SE. In Iraq with the army and cannot see anything thru the view finder. Batteries are in and hand control functions. Caps are off. Scope will adjust with hand controller


First you must line up the small finder scope with the main tuibe--

Point the scope at a distant object like the top of a telephone pole. Center the top in the eyepiece of the main scope-- then without moving the scope center the red dot on the same exact spot on the telephone pole.

Also practice focusing 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. Turn the fopcus knob slowly until the object comes to focus.

The Celestron Nexstar 4SE makes a weird cracking noise when you press the left or right arrows on the controller. I tried taking it off of the tripod, and it still will not rotate left or right, even if...


Is the AZimuth clutch locked down? Then either a gear is broken inside or the worm gear inside has slipped and is not engaing. You can return these to Celestron for repair, here:

Start Align with NexStar 4SE


Did you enter the correct TIME, DATE, and LOCATION? and yes you may have aligned on to the wrong stars -- they need to be "near" the center.

I recently bought the Celestrobn 6SE. I can opperate teh telescope itself..but have no idea what the software is about what on earth is a nextour software all about, I havent a clue..AND what is the...


Hi there,

I have also recently bought a Nexstar but mine is a 4SE. Im still pretty new at it myself but from what I understand, the Nexgps software is just the computer software to control the GPS unit from your PC - the same as the NexRemote software. If you dont have a GPS unit you have to purchase it as an extra so the software will only be useful if you have GPS.

The Nextour is just software that allows you to add objects you wish to see that the telescope will take you too in tour mode. Once you have it aligned of course.

I see this post was almost a year ago so you probably know all this by now.

Do you have any problems using the star align? Im really battling - gonna try 2 start align because it doesnt quite know where it is when I do the 3 star align.

Regards,
Bianca

The hinge should be to the north. An imaginary line drawn perpendicular from the center of the tilt plate should point to Polaris (the North Star).
