Where is the declination clutch located?


RA moves the polar axis--- and DEC moves the scope from side to side.

There are two knobs that turn these two axis.

Converting between Forms When working with phasors it is often necessary to convert between rectangular and polar form. To convert from rectangular form to polar form: M = sqrt{A^2 + B^2} f =...


You can switch the display mode for complex numbers by pressing SHIFT MODE down 3 and picking one. This will display the current result in the selected mode.

You can also override the current display mode and specify the format. Add these keystrokes at the end of a calculation: SHIFT 2 then 3 for polar or 4 for rectangular.

Polar alignment with cg5 mount in the tropics


Wait what? You just have to remove the front bracket for the alt screw and you can go lower than 30 degrees.

I don't know how to use the motor and the image is upside down


All astronomical telescopes have upside down images. No up more down in space, and MORE glass is needed to erect the image which decreases the light.

If your scope is like the one in the picture it is an equatorial mount which must be polar aligned to work. Once the scope is roughly polar aligned the motor will keep the object in the eyepiece for a long period of time. It moves the RA axis in time with the movement of the stars across the sky.

HOW DO I USE THE TELESCOPE


Hi,

he first thing you will need to know is does your telescope have a polar axis or not, that is, is it intended to track, or is it merely a point and look, or what we call Alt-Az. Alt means altitude and Az means azimuth, where Alt is the distance above the horizon, and Az is the direction in a circle around the horizon. If you have an Alt-Az mount, just skip the polar alignment step. If you have a polar axis, that is, your telescope is intended to track the stars, then find north, and make sure the polar axis is approximately lined up in that direction. It does not have to be too accurate, but make sure it is pointing pretty close to north. If you are not sure where north is, either use a magnetic compass, or try to find Polaris, the North Star.

Thanks.

Can't transform from polar to rectangular


Hello,
The e is the same, it is the exponential. According to Euler's relation
e^(i theta) = cos(theta) + i sin(theta), where i is the imaginary unit.
When represented on the complex plane (x,iy) the point (cos(theta), sin(theta)) is at the extremity of a vector of length 1 and making an angle theta with the real axis.

In (plane) polar coordinates, a point is defined by the radius r, and the angle, theta, it makes with the x axis, measured in the trigonometric (counterclockwise) direction. It is structurally equaivalent to representing it in the complex plane as r*e^(i*theta). Since r is the measure ot is radius, and the theta is it argument (angle). The complex notation is used for its convenience when adding vectors (as is AC circuits)
That is the theory.
I am inserting a clipping from the book to show you how to convert between polar and rectangular coordinates.

There Is No Power For The Axis 9


that sounds bad. You will need to get someone to have a look at the decks for you. The fact that both blew sounds like they got a major power surge or are on the wrong mains voltage. check to see that they are setup for operation in your country. Check your mixer for damage also.


Some suppliers of electricity are bound by regulations to keep supply within 5%. When you have a spike that "blows" stuff, they generally know about it and there may be some recourse with the electricity provider. Worth checking out.
