I have a celestron Cosmos 90 GT Wifi telescope and so far haven't been able to use it. I struggle with aligning the telescope to 3 bright stars... if by chance it says its aligned when I choose a star


Aligning a scope requires several things to be correct.
1. You must follow the setup in manual 100%
2. You must pick the correct alignment stars. Most failed alignments are because you aligned on the wrong star. So alignment requires you to learn the names of a few bright stars and be able to spot them in the sky.
3. With many goto scopes there might be a "home position" to start the alignment. For example, tube pointed roughly North, and level. Check your manual for a "home position. Also time, date, and site must be correct.

Clear skies,

We purchased a 78-5880 North Star for our son for Christmas. I have skimmed the manual, but the family wants to dive in and begin using. They are wanting to take it back because they have been unable to...


All of Bushnells manuals are on this web site:

Usually there is a setting in the hand controller to adjust brightness. Make sure the batteries are FRESH and new. Put the eyepiece with the largest number written on it into the diagonal. DO NOT use the 2x barlow if you have one.

I have a meade lx200gps 10" scope. The ra up is not responing. the down is working only. After initializing and fining north the auto star says stalled motor.


Do a calibrate motors and make sure you are using a separate 12 volt power pack or BRAND NEW internal batteries. All goto scopes work better with smooth, regulated power. The internal batteries will NOT work well for very long.

The Calibrate motors routine adjusts the motors for the power supply being used.

Meade LX200GPS The scope does not complete the 'Auto Alignment'


Once the scope has taken a GPS fix and knows TIME, and SITE, and you do a two star alignment your alignment stars overide any automatic alignment issues.

You could turn off the GPS put in Time, Date, and Site, do a two star alignment and everything would be fine. Centering the alignment stars is the "trick". Apparently the scope also finds NORTH OK, or the alignment stars would be way off. Since you pre-level the tripod already the software can FAIL on "tilt" and you still get good gotos.

I would not worry about it, especially since your gotos seem perfectly fine.

In need of a manual for a orbitor 3500 telescope


Is this your telescope?
http://ottawa.kijiji.ca/c-buy-and-sell-hobbies-crafts-Orbitor-3500-Telescope-W0QQAdIdZ200032598

If it is--- this is a simple REFLECTOR telescope on an equatorial mount. The mount must be polar aligned to Polaris in order to use it. See my TIPS on my profile page for instructions on aligning the mount on the North star Polaris.

You will not find a manual -- however Meade makes a very similar telescope and they post all of their manuals on this web site.

I believe this one is VERY similar to your telescope.
http://www.meade.com/manuals/TelescopeManuals/Reflectors/062002Jupiter114EQ-D.pdf

Here is the page with all the manuals. Look under 4.5 inch REFLECTOR header and download one for free. They all assemble and are used the same way.

Also read my TIPS on my profile page.

Good luck.

I need simple set up instructions for australia


All GOTO scopes require a setup routine-- on my ETX 90 I must--

1. Train the drives

2. Set the time and the date, and the observing site in the hand controller

3. Level the tripod and the tube

4. Point the tube NORTH

5. And align and center on two stars BEFORE the telescope will find anything.

Read the manual TWICE--- and then practice inside before you take it outside at night.

Celestron telescope


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).

You must CENTER the alignment stars -- usually they are near -- but may not be inside the eyepiece.

Centering the two stars makes the GOTOs accurate.

Make sure time, date, site, is correct--- and if your scope has a "training" routine in the manual--- be sure to do it.
