How do you use a reflector telescope?

Answer 1

The magnification of any reflector telescope is given by the focal length of the mirror divided by the focal length of the eyepiece, so if the mirror's focal length is 1000mm and the eyepiece has a focal length of 10mm, then the magnification is 1000 / 10 or 100 X magnification. So, if you wish to increase the magnification you need to either change the mirror (which is impractical) or change the eyepiece (which is easy) replacing it with an eyepiece with a shorter focal length. So, if the new eyepiece has a focal length of 5mm then the magnification is 1000/5 or 200 X magnification. If you do not wish to buy an expensive complete set of eyepieces, you can buy what is called a Barlow lens which fits between the eyepiece and the telescope. These can increase the magnification by a factor of 2 or 3, but the quality of the image is not so good (as the light has to pass through the Barlow lens as well as the eyepiece). Do not forget that you cannot keep increasing magnification hoping to get better and better images. As you double the magnification, you cut the light entering the telescope by at least a half, so the image is dimmer. Most small telescopes with mirrors between 6 and 8 inches can magnify up to around 100 X effectively but anything more than this will result in the image becoming progressively darker, more grainy and generally not so clear. To get higher magnification you need much bigger mirrors of 10 or 12 inches or more. To add further complications, you will also need a substantial mount for the 'scope as any small vibration at a high magnification will result in a great deal of image shake. Also, you will need a really good motor drive to compensate for the movement of the earth, as, without such a drive at high magnifications, the image will move out of the field of view almost as quickly as you find it due to the earth's motion.

Answer 2

Using a Reflector TelescopeLook through the eyepiece and focus the image with the focus knob. To target, point it at whatever it is you are trying to see.

A reflector type telescope always inverts the image, unless of course you are using it for star gazing, then it doesn't matter. However, if you are using it to view a planet you must remember you are looking at the object upside down, unless of course you have a correcting prism installed in your eye piece holder.

Answer 3

The very best, most accurate, most precise, and most helpful suggestion we can

give is that you take the time to read and understand the manual (the book) that

comes with the instrument. If you bought it second-hand and no manual came

with it, then you really should contact Meade, give them the model number and

serial number of the one you have, and get a new manual from them, even if they

charge you something for it.
