Astronomy with a smartphone:

It all began with telescopes of the series Nexstar Evolution: Celestron equipped this series with WIFI, so that they can be controlled via mobile units by using the SkyPortal app.

The graphic user interface offers many possibilities and can be intuitively controlled. The omission of a hand controller is another benefit of controlling the system via an app. This way one needs only a limited amount of equipment.

Now available: The new AZ-GTi from Skywatcher:

The mount AZ-GTi GoTo WiFi from Skywatcher is completely new. It carries telescopes with a weight of up to 5 kilogrammes, which can be directed to almost 10,000 sky objects via a smartphone using the SynScan app.

With this GoTo control even beginners will easily find their way around the sky. The mount not only swings the telescope to the desired object, but also keeps on tracking, keeping the object in the eyepiece, despite the earth’s rotation.

The mount AZ-GTi is an azimuthal mount, which, in contrast to an equatorial mounting does not permit astrophotography with longer exposure times. However, azimuthal mounts are smaller, lighter and ready more quickly for use than equatorial mounts.

Skywatcher AZ-GTi telescopes:

Skywatcher currently offers the AZ-GTi in three sets. The most inexpensive set is the Explorer-130PS AZ-GTi. Here you can obtain the mount with a Newton telescope and an aperture of 130 millimetres. The combination is not only more reasonable in price, but also has the biggest mirror optics and thus the highest light gathering capacity.

The combination with the 127mm Maksutov is also very interesting: SkyMax-127 AZ-GTi GoTo WiFi. Despite its high focal length, the Maksutov still has a short tube and, as a closed system, is almost indestructible.

An app for the mobile unit offers more possibilities than a hand controller, and the smartphone is always close at hand. Controlling the system via smartphone makes sense especially for small mounts.
