but I've skipped them in this tutorial since this is more of an introduction to the methods of altitude tracking. For a quick and relatively accurate estimation of altitude, the elevation-angle-only method works well. Other methods, such as the alt-azimuth tracking method, often require multip...
Dobsonian telescopes are a type of Newtonian reflector with a simple tube and alt-azimuth mounting (see "Telescope Mounts"). They are inexpensive to build or buy because they are made of plastic, fiberglass or plywood. Dobsonians can have large apertures (6 to 17 inches, 15 to 43 centimeter...

The mount's onboard computer uses the 3 star's locations to calculate the polar misalignment, and the alignment error between the OTA and the polar shaft, It also allows the computer to orient itself in relation to the sky, to ensure reasonably accurate gotos to other requested objects in i...
full-circle protractor for more advanced calculations. The number of degrees indicated by the arrow (the distance the upright post was turned away from 0 degrees to sight the object) is called an azimuth. This principle is used in many practical ways, including navigation, mapping and astronomy...
(and how to identify them)by Martin J. Powell"This morning, the ultimate dream of a planet watcher was come true: all of the planets condensed before me into one straightforward, nowhere peripheral view. It struck me like nine-branched lightning, held me still as a (deeply breathing) ...
To calculate the shade value, first the altitude and azimuth of the illumination source are needed. These values will be processed with calculations for slope and aspect to determine the final hillshade value for each cell in the output raster. Hillshade algorithm The algorithm for calculating the...
enough to capture the light of the brightest astronomical objects, including the moon, planets and stars. This telescope includes an altitude/azimuth tripod mount and a 5x optical finder scope. It also comes with two eyepieces and a 3x Barlow lens for viewing astronomical objects at several diff...
(s) above you can graph XYZ values on a 2D graph in X and Y. The numbers needed are your original X, Y and Z values (OX, OY, OZ), Azimuth (X rotation) and Altitude (Y Rotation). Once your formulas are placed you adjust the rotations and watch as the graphed X and Y values ...
It has all to do with the mount. if a mount tracks the movement of the sky it can prevent the streaking you are asking about. an Equatorial mount will track in one axis and an Altitude/Azimuth will track in two. with an Alt/Az the image will rotate unless the camera is rotated too...
