Question about Bushnell Voyager 78-9945 Telescope

1 Answer

Altitude dial The pointer on the altitude dial does not rotate with the up and down movement of the telescope's main barrel or tube. It slips. I had this problem with my first telescope and Bushnell replaced it with a new telescope under the warranty provisions. The replacement telescope has exactly the same problem right out of the box.

Re: altitude dial

The altitude scale on these small telescope are virtually useless and cannot help you find objects in the sky--

Don't worry about it --- just use the scope and a star chart to find things in the sky. A free monthly star chart that you can download is available here:

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:

How to use orbitor 2010 telescope

This is a small reflector style telescope on an Altitude Azimuth mount. There are no specific manuals on the internet; however other manufacturers make the same telscope and they are all assembled and used the same way.

Here is Meade's similar telescope:

The tube is identical.

The finderscope for the Bushnel 78-9930 telescope will not align w/ the telescope. The Azimuth adjustment knob bottoms out before the alignment is achieved. Everything is molded one piece. Besides the...

Obviously the mounting for the finderscope is NOT parallel with the tube-- probably the screw holes were not drilled correctly.

This is one of the reasons why we never recommend Tasco or Bushnell telescopes. They are considered "toy" telescopes and most of them are not suitable for Astronomy.

Return it and buy one of these:

OR re-drill the holes so the finder scope is more parallel with the main tube.

ETX 60 altitude doesn´t work, but motor works

You need to tighten the friction lock - it acts as a slip clutch.

My telescope vibrates a little, i checked it and found out the altitude holder is a little lose... how do i fix it?

Read my TIPS on my profile page; about improving a "department store" telescope.

The vibration is because the tripod and mount are too small to support the tube. NEVER buy a scope from Craigslist or Wal Mart, or Ebay, unless you know exactly what you are buying.

The Azimuth Dial isn't firmly attached cause altitude cannot be fixed to an angle

Most of the small telescopes setting circles really cannot be used to find anything--- just not accurate enough---

Try using a star chart -- and star hopping --- to what you want to see.

Azimuth motor gearing problem

Sounds like it could be that the worm gear is not meshing
Look here for guidelines in the internals

Azimuth motor gearing problem

I also purchased a used Meade ETX-70, only to find it had the same problem with the rotation axis motor running but no movement. After removing the bottom cover, I found the motor w/worm gear would not contact the main rotation gear. I solved the problem but purchasing a small 3/8x3/4x.032 spring that I had to custom fit to hold the motor w/worm gear against the rotation gear. Take caution not to have the spring apply to much pressure or it will cause to much drag.
To gain access, remove the bottom round cover(it will just pop off).
Then use a small .05 allen wrench to remove the set screw in the horizonal chrome lock. The chrome lock fits over a 1/2" bolt. By removing this bolt you will remove the washer/bearing assembly. After removing this, you will see a nylon nut, use a 11/16 socket to remove. Becareful, it is a fine thread and you don't want to cross thread it!
After you remove this, you will be able to remove the bottom housing, which will expose the motor and gear. You should be able to see what I am referring and where to place the spring.
If you can make it this far, then you should be able to install the spring. I used a little small dab of Gorilla glue to hold it in place, since the spring will have enough constant tension to keep it from moving.
I'm not sure if this was a design flaw, but I got no help from the Techs at Meade, only that they would upgrade to a ETX-80 for $149.99 plus shipping.
Hope this helps.......
