Mirrors are probably NOT out of collimation. You cannot apply more than 50 times aperture to any telescope. Your scope is about 3.5 inches so about 150-160 power is the maximum and then ONLY on the most stable transparent nights.

Watch this video if you want to learn about collimation of the mirrors:

I cannot focus my se8


That is a good telescope. I am unsure about what adjustments you are trying out, so please excuse me if I get too basic here:

The focus adjustment will not give you an enlargement, it only brings objects to a sharp image. I trust that is OK for you.

To gain an enlargement of something, you must use a different eyepiece with a shorter focal length, say from 25mm to 12mm. The magnification you will get is the focal length of your scope, 2032mm, divided by the focal length of the eyepiece, say 2032/25, giving you magnification of x81 with that eyepiece.

There is a practical limit to this, which for your scope is about x400, (an eyepiece of 5mm) in excellent conditions at the top of a mountain. For terrible seeing from a suburban backyard, it will be say half that, x200, or an eyepiece of 10mm. You will get the best viewing with a magnification of say x150 at the most, or an eyepiece of 15mm. Less is more.

Then, you will not ever see the true disk of a star with that scope, they are too far away. You will however magnify the image of a planet, star cluster, nebula, or binary star pair. Sometimes though that will be at the cost of image clarity, it depends on where you are at the time.

Jupiter is not up in the sky right now, during the evening-- however Saturn is up. All the planets follow the ECLIPTIC path across the sky-- the same path the sun followed during the day time.

Objects in the night sky are VERY SMALL-- smaller than the tip of your finger held at arm's length. Tonight try to find M42 the Orion Nebula, and M45 the Pleiades star cluster. See the sky map above.

How do i use it..??? and how do i locate planets in the sky


Planets travel across the sky on the same "path" that the sun took during the day. This is called the ecliptic (path of the sun.

Jupiter is up after dark and is VERY bright -- point the telescope to the BRIGHTEST "star " in the sky after dark.

National geo telescope viewing saturn whats the chances


You can see Saturn it will be small however.

You can see Saturn WITHOUT a telescope -- it looks like a star in the sky. Download the free planetarium software Stellarium and it will show you what is up in the sky for any time or date. All of the planets follow the ecliptic across the sky-- the same path that the sun makes across the sky.

Saturn is in the Southeast after dark right now.

A fuzz sound is coming across my speakers. How


Try and isolate the problem by disconnecting all components and reconnect them one by one. Fuzz could be comming from one particular component, or could be an internal fault in the bose amp.
Good luck!

The telescope doesnt go up it goes down


I assume you are using the 497 hand controller? Planets will always be a little bit OFF since their orbits are calculated. You should be able to see Venus, Jupiter, and Saturn as a disk-- the other planets are very tiny and can be mistaken for a star.

Use the Automatic alignment feature and center the brightest nearest star. It will not be in the eyepiece. Be sure you calibrate motors, and train the drives, and the time, and date and site are accurate.
