Question about Celestron NexStar 4 SE Telescope

1 Answer

Start Align with NexStar 4SE

Im really new at all this. I have managed to focus on various object etc on my own but I cant seem to get the sky align to work.
I focused on 3 bright starts and followed the instructions to Align each of them. It said alignment was successful but when I ask to see the moon (just to check that the alignment had worked) it was way off.
Do I have to make sure each star is exactly dead-center of the lens? Also, Surely if you take some time to get to the 3rd Alignment star the alignment would have changed with the earths rotation?
Im in South Africa - Cape Town. Not sure how to get around this. I have tried it a few times and its always way off.
Also, does any-one have advice on which extra lenses are really worth while? I would love to be able to see more of DSO's than just the stars and planets and will definately invest in the right stuff if it makes a noteable difference - can any-one give advice on what they have been able to see with additional lens?

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.

Why can I not see the difference from the sky and a star even when I allign my laser well?

It sounds like you have not adjusted the focus properly. I recommend you take your telescope outside in the daytime and point it toward a building or tree or hilltop that is somewhat distant from you. The exact distance is not important, but it should a block or more.

With the telescope pointed at the distant object, focus the telescope until the object is sharp and clear. The object might appear upside down -- that's normal for many astronomical telescopes. When you have achieved a sharp focus, leave the focus control alone until you are outside at night under the stars.

The focus should now be fairly close for viewing stars and planets. Small adjustments of the focus control may still be necessary for the sharpest view.

I cannot see anything through the lens of my brand new 6 SE. What should I do?

During the day, point the telescope at a part of the landscape about 100 yards away. Use the lowest power eyepiece (highest number) in the focal tube. Center the landscape object in the telescope. Align the finder scope so that it points exactly where the main telescope is. At night, leave the scope out to reach thermal equilibrium (about an hour). Point the finder at the moon. The moon should be in the main scope also. Practice finding the moon before you start on the planets Once you are comfortable with the moon and planets, you can go for the deep sky objects

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.

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.

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.

I got an inphase telescope for a present secondhand. There are no instructions and I have never used one before, could you advise me please?

The bit of information I can find on this model tells me this scope is probably a Newtonian reflector Telescope.

The following is the most basic steps I can think of to get you in the driver's seat.. by doing a few simple internet searches in regards to astronomy.. you should be able to greatly expand on my few simple tips.

The primary mirror is at the bottom.. the heavy end.. of the tube... if you can see screws holding it in place... resist the urge to "tighten them up".. doing so will probably misalign the mirror.

You should have a small finder scope mounted on the side

Near the finder scope will be the eyepiece/holder with focuser.. all this should be closer to the skyward end of the scope than the earth end of the scope.. so to speak.

As you peer into the eyepiece you are basically looking at a right angle to the primary mirror into a smaller secondary mirror which in turn is reflecting the image of the primary (bottom) mirror. By adding various eyepieces with different magnification factors you are enlarging that image.

Most folks don't realize how bad a typical looking glass mirror is..but if you look really close at the old bathroom mirror.. you will see how much the glass distorts the image reflected on the silver coating.

Which is why your telescopes mirror has a top coating of silver on the glass.. not behind the glass..

To get started..

I suggest doing all of the following things during daylight hours or near dusk on a clear nite so you can see what you are doing.. to get familiar with the scope.

Using the lowest powered eyepiece you have.. once inserted into the focuser .. aim the telescope at an object a few hundred yards away and attempt to focus..

Remember that everything will be upside down.. looking at the moon, planets and won't really matter.

Once you have managed to point and focus easily.. you can align your finder scope.. again.. using a fixed terrestrial target

Aim the scope at this object.. the further away the object is.. the better.. get the object as close to center as possible.. slightly increase the magnification if you have a stronger eyepiece.. if not.. proceed.

Fix the scopes position by tightening any set screws on the mount.

Check the position of the spotted object again ..make adjustments until you have the object centered.

Look through the finder scope.. adjust the mount screws until the object is centered in the crosshairs..

Check all settings.. your done.

Start out looking at the brightest objects in the nite sky using the lowest magnification..

Once you become familiar with how to find/spot and focus on simple bright objects.. like the moon and perhaps Jupiter... you can read various articles at websites such as Sky and Telescope to learn how to properly align your scope with the polar (north) star.. of course this depends on the type of mount.. and drive if any... Or simply enjoy point and look backyard astronomy.. some of my most fun star gazing has been using bincoulars.. a star chart.. and a lounge chair.

Remember to keep it simple at first.. be ready to dress warm.. and take your time.. your eyes will need almost 30 minutes to really adjust to nite this cooler weather it helps to let the scope cool down for a while outside (covered) to keep things aligned properly.. of course the darker it is the better the view..

Even inexpensive scopes can give a lot of satisfaction to a point... especially if it's your first..

Good luck!

Cant see ****

Cannot see anything in the daytime? We need more details.

Put the eyepiece with the largest number written on it into the focuser. Try focusing on a distant object during the day time.

You must follow the setup procedures in the manual for accurate GOTO function at night.

Cannot see light through the eye piece--do i have to align first

NO, you should be able to see through it without alignment. Put the eyepiece with the largest number written on it into the DIAGONAL put the diagonal into the rear of the scope and practice focusing on a distant object during the day time.

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.

I can go through the Sky Align procedure and the telescope will not find an object for which it has been tasked (ie. the Moon). I have triple checked the time, lat/long, etc. and still no luck after many...

Is the mount level? Did you center both alignment stars?

Are you running it off of fresh batteries or an outside power pack? 10 degrees sounds like Daylight Savings time is set to YES instead of Standard Time.

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.
