Orientation or Autonomous Field Detection (AFD)
What is AFD?
Autonomous Field Detection (AFD) is an algorithm that accurately identifies any object in
the telescope’s field of view by using an internal map containing tens of millions of star
coordinates.
What does AFD do?
AFD automatically points to objects in the night sky, making it easier to look for targets. It
also provides information about what you are observing, such as the distance from Earth,
the size, the age, and more.

What is the puprose of a dark frame ?
In digital photography, taking a dark
frame means recording an image
with no signal or noise. This process
improves your observations as well
as the quality of your images. A dark
frame enables the telescope’s onboard
computer to analyze and correct the
sensor’s inherent electronic noise.
How do I take a dark frame?
To take a dark frame, leave the cap on the telescope and make sure that you
are in a dark place. Do not expose the telescope to direct light.
Go to the user tab: My eVscope.
If an error message appears, try again later, ideally in a darker setting. It may be that too
much light was detected on the image.
Noise can occur during long exposures
or strong variations in temperature. The
appearance of hot pixels (red, blue or
green spots) on your images can reveal
the effects.
At what frequency should I take a dark frame?
Dark frames can be taken at any frequency you like. We recommend taking at least
one in the winter and one in the summer, as changes in temperature and altitude can
cause imperfections in the images. A dark frame should also be taken before each
scientific observation.
