What are alt-azimuth and equatorial mounts?
What are alt-azimuth and equatorial mounts?
Alt-azimuth mounts track in iterative up/down – left/right movements. Equatorial mounts are essentially alt-azimuth mounts but tilted at an angle based on your GPS longitude. This also corresponds to the altitude at which the north star (Polaris) sits in your sky.
Is an equatorial mount worth it?
An equatorial mount solves this problem. It can perfectly track the stars as they move during the night, and you only need to adjust one axis. Of course, if you want to do any long-exposure photography, like longer than a few minutes in a photo, you absolutely have to have an equatorial mount.
What is a German equatorial mount?
German equatorial mounts or GEMs track an object using constant speed movement on one axis that is oriented parallel to the Earth’s axis of rotation. This makes the design ideal for astrophotography.
What are the two advantages of an equatorial mount over an alt-azimuth mount?
These mounts are good for terrestrial observing and for scanning the sky at lower power but are not for deep sky photography. It can track continuously across the meridian, which many German mounts cannot do. Because it has very little or no counterweights, it’s also lighter and more portable.
Which is better a refractor or reflector telescope?
If you are interested in astrophotography, purchasing a refractor is a better option because of it’s specialized optic design that captures deep space objects like galaxies and nebulae. If you are interested in brighter celestial objects like the Moon or planets or a beginner, a reflector telescope is ideal.
How do you read az alt?
(not shown on the diagram), at 90° to the principal vertical. from the north cardinal point to the vertical circle through X, measured 0°-360° westwards (clockwise)….Positional Astronomy: Coordinate systems: the horizontal or “alt-az” system.

Do equatorial mounts track planets?
If you are reasonably close to the correct polar alignment (meaning you don’t have any issues with tracking simple stars) then an equatorial mount will track pretty accurately to the planets.

What is a skywatcher mount?
Equatorial mounts usually come as German equatorial or fork mounts. They both use a wedge set at an angle equal to the observer’s latitude, in order to point to the celestial pole. Sky-Watcher SynScan mounts provide extremely high precision tracking and have built in autoguider ports. …
What is the equatorial mount on a telescope?
An equatorial mount is a mount for instruments that compensates for Earth’s rotation by having one rotational axis parallel to the Earth’s axis of rotation. This type of mount is used for astronomical telescopes and cameras.
